System and method for managing security for a distributed healthcare application

ABSTRACT

A system and method for managing security for a distributed healthcare system, such as a system for placing laboratory orders and receiving test results. The network of healthcare businesses that use the system is referred to herein as a Health Data Network, or HDN. When the user log on to the system, the user connects to the system on behalf of a Health Data Network (HDN) Business. Through the user&#39;s user account, the user is linked with HDN Businesses. The user may be allowed to log on to the system on behalf of more than one HDN Business. If the user&#39;s practice has more than one location or business unit, and all orders and results are shared throughout the practice, the user&#39;s practice may be configured as a single HDN Business. In this case, the practice&#39;s data may be stored in a central location and can be accessed by all users who have the appropriate permissions. However, if the user&#39;s practice has more than one location or business unit, and the need exists to keep orders and results isolated within a location or business unit, the practice may be configured in a parent-child HDN Business relationship. In addition to the ability to log on to the system on behalf of an HDN Business, users also must have permission to actually use the many functions of the system, and need access to the data stored across the HDN. As part of creating the user&#39;s permission profile, the user is assigned a role that the user performs when working with the system. This includes information regarding the types of data the user needs to be able to access and the functions the user needs to carry out on that data. Types of data are referred to as objects and functions are referred to as operations. Patient records, lab requisitions, lab results, test codes, ICD-9 codes, lab profiles and physician profiles are examples of objects. An example of an operation is adding new objects. Viewing, modifying, printing, and deleting existing objects are also examples of operations. The process of searching for existing objects is also considered an operation. A role defines what objects a user can access and what operations a user is allowed to carry out on each of those objects.

PRIORITY CLAIM

[0001] This application claims benefit of priority of U.S. provisional application Serial No. 60/167,532 titled “System and Method Enabling a Distributed Object-to-Relational Application Framework”, filed Dec. 1, 1999, whose inventors were Robert Yeager, Kurt Schurenberg, and Robin Johnson.

FIELD OF THE INVENTION

[0002] The present invention relates to the field of distributed systems and applications, and more particularly to a system and method for managing security for a distributed healthcare application.

DESCRIPTION OF THE RELATED ART

[0003] The healthcare industry has historically suffered from information flow and workflow fragmentation. Information is typically exchanged among various parties involved in healthcare, such as physicians, hospitals, insurers, laboratories, employers, and others, using paper-based methods. As is well known in the art, such methods are inherently labor-intensive, inefficient, and error prone. Although efforts to modernize healthcare by utilizing electronic information networks have been undertaken, so far these efforts have failed to achieve the promised integration of members of the healthcare industry.

[0004] One area of healthcare in particular that has historically suffered from inefficiencies pertains to laboratories, such as labs that perform clinical tests ordered by caregivers. From collecting a specimen to reporting results, laboratories traditionally have been burdened with heavy user intervention and paperwork. Specimens along with the laboratory orders must pass through many hands before tests can be performed. Numerous pieces of paperwork must be properly filled out and forwarded to the performing lab to ensure that the proper tests are performed on the proper specimen and to ensure that necessary clinical information accompanies the order. The integrity of the results returned to the caregiver is based on the ability of the caregiver and the performing lab to properly submit accurate test requisitions, track specimens, and synchronize reported results with submitted requisitions. Any breakdown at any point in this workflow can cause specimens to become lost, tests to be delayed, and results to be erroneous. The situation is further complicated when a caregiver interacts with multiple laboratories.

[0005] In addition, for laboratories to continue generating revenue, accurate and complete billing information must accompany the laboratory order. Without the necessary information, laboratories are faced with absorbing the costs of their services. Furthermore, billing information must be received by the laboratory in a timely fashion in order for the collection process to be initiated and completed within the given amount of time according to regulations.

[0006] FIGS. 1A-1B are a flowchart diagram illustrating a typical workflow among various parties, as known in the prior art, when performing one or more laboratory tests for a patient. Several disadvantages are associated with such a workflow. To name a few:

[0007] Hand writing the paper requisition form is time-consuming and error prone.

[0008] Different requisitions have to be completed for orders that are to be sent to different laboratories.

[0009] Patient may lose the paper requisition form(s) en route to the specimen collection station.

[0010] Phlebotomist and accessioning clerks must visually match the specimens to the requisitions without electronic verification, possibly resulting in incorrect specimen identification.

[0011] No electronic verification of information prior to specimens and requisitions being picked up by the courier.

[0012] Result delivery traditionally is not timely. Laboratories may utilize fax machines, teleprinters, mail, courier services, or phone calls to deliver results. However, the results are not usually available to the customer as soon as they are entered in the laboratory's laboratory information system.

[0013] Lab results which are misplaced, destroyed, or not received as scheduled, must be retrieved from the laboratory information system and delivered to the ordering physician by the laboratory.

[0014] Paper requisitions must be manually maintained to keep track of the patient's lab orders, possibly resulting in misplaced orders.

[0015] Patient may supply incorrect insurance information, possibly resulting in inability of lab to be reimbursed for services.

[0016] Preprinted requisitions have to be stocked and become outdated, listing tests which have been discontinued or modified.

[0017] In order to address the particular problems outlined above, as well as various other well known problems in the healthcare industry, it would be desirable to integrate various healthcare businesses into a Health Data Network (HDN). However, the security of this network, including access to it, is critical because the system may provide access to confidential patient information, including laboratory test results and medical history. Thus, a system and method for managing security for a distributed healthcare application are described below.

SUMMARY OF THE INVENTION

[0018] One embodiment of the present invention comprises a system and method for managing security for a distributed healthcare system, such as a system for placing laboratory orders and receiving test results. The network of healthcare businesses that use the system is referred to herein as a Health Data Network, or HDN.

[0019] Before the user can log on to the system, the user must have a user account including a logon name and a password. The user account provides the needed security for controlling access to the HDN and identifies the user while the user is using the system.

[0020] When the user log on to the system, the user connects to the system on behalf of a Health Data Network (HDN) Business. An HDN Business is any business, including a hospital, clinic, physician office, laboratory, payer, or employer, that participates in the creation and sponsorship of a specific HDN.

[0021] Through the user's user account, the user is linked with HDN Businesses. The user may be allowed to log on to the system on behalf of more than one HDN Business. For example, the user's primary HDN Business may be the office in which the user is currently working, but there may also be times when the user may need to access the system on behalf of a hospital where the user has patients in order to check on their status. In this case, the user may be linked to both HDN Businesses, the user's office and the hospital.

[0022] Parent-Child HDN Businesses—If the user's practice has more than one location or business unit, and all orders and results are shared throughout the practice, the user's practice may be configured as a single HDN Business. In this case, the practice's data may be stored in a central location and can be accessed by all users who have the appropriate permissions.

[0023] However, if the user's practice has more than one location or business unit, and the need exists to keep orders and results isolated within a location or business unit, the practice may be configured in a parent-child HDN Business relationship. This prevents lab orders and results and other data associated with one location or business unit from being accessed by users logged on to other locations or business units of the practice.

[0024] 1. A parent HDN Business is created for the entire practice.

[0025] 2. Child HDN Businesses are created for each business unit or location. Some business units or locations may actually share a single child, while others may be set up as individual child HDN Businesses.

[0026] 3. All child HDN Businesses are linked to the single parent HDN Business.

[0027] 4. The user's user account is associated with each child HDN Business where the user are permitted to access the information. The user's account may not be associated with all child HDN Businesses for the practice. Some advanced users may have their account associated with the parent HDN Business so they can carry out global administrative functions.

[0028] The data for the user's practice is then stored at two levels:

[0029] 1. At the parent-level, the following information is stored and available to all child HDN Businesses of that parent HDN Business:

[0030] Patient records and supporting information, excluding orders and results

[0031] Payers

[0032] Providers and caregivers

[0033] Codes, including diagnosis codes (ICD-9), test codes, analyte codes, report codes and profile codes

[0034] Report groups, patient groups and test groups

[0035] System configuration

[0036] When the user add any of these items to the system, they are available to all child HDN Businesses associated with the parent HDN Business.

[0037] 2. At the child-level, the following information is stored on behalf of and is only available to users logged on to that child HDN Business:

[0038] User preferences

[0039] Orders

[0040] Results originating from orders transmitted on behalf of the child HDN

[0041] Business

[0042] The orders, results and user preferences for each child HDN Business are isolated from the other child HDN Businesses. The only way a user can access this information is to log on to the child HDN Business. If the user are logged on to the parent HDN Business and have the appropriate permissions, the user can access all information for the practice, including the orders and results stored specifically for a child HDN Business.

[0043] Permissions, Roles, Operations and Objects

[0044] In addition to the ability to log on to the system on behalf of an HDN Business, users also must have permission to actually use the many functions of the system, and need access to the data stored across the HDN. As part of creating the user's permission profile, the user is assigned a role that the user performs when working with the system. This includes information regarding the types of data the user needs to be able to access and the functions the user needs to carry out on that data.

[0045] Types of data are referred to as objects and functions are referred to as operations. Patient records, lab requisitions, lab results, test codes, ICD-9 codes, lab profiles and physician profiles are examples of objects. An example of an operation is adding new objects. Viewing, modifying, printing, and deleting existing objects are also examples of operations. The process of searching for existing objects is also considered an operation.

[0046] A role defines what objects a user can access and what operations a user is allowed to carry out on each of those objects. For example, one role may allow users to add, view, modify, print and delete lab test requisitions, while another role may only allow users to view and print lab test requisitions.

[0047] When a permission profile is defined for the user, it is specific for an HDN Business. If the user belongs to more than one HDN Business, the user may have more than one permission profile. Each of these profiles may be different. For example, the user may have permission to add, view, modify, print, and delete patient records on behalf of one HDN Business, but the user may only have permission to view and print patient records on behalf of another HDN Business.

[0048] Effective dates and expiration dates may also be set for each permission profile, creating a limited period of time when that permission profile is in effect. This can be useful, for example, if a first user is going to be temporarily out of the office and the first user needs to be able to allow a second user to do the first user's work while the first user is gone. The permission profile for the second user can be set to begin the first day the first user is out of the office and to expire at the end of the day before the first user returns.

[0049] An administrator may work with users to ensure that the permission profiles and roles selected for each user are sufficient to meet the users' job requirements.

[0050] When the user logs on to the system, the user is connected to the HDN on behalf of an HDN Business. The user may select a default HDN Business at login time. For example, after entering a username and password, a popup window may appear with a list of HDN Businesses to choose from. Once the user log on to the system, a message at the bottom of the screen displays the name of the user's current HDN Business. The Change Active HDN Business menu option of the User menu enables the user to select another HDN Business after the user has logged on to the system, provided that the user has permission to access more than one HDN Business.

[0064]FIG. 2—Health Data Network

[0065]FIG. 2 is a block diagram illustrating an exemplary Health Data Network (HDN) including electronically connected healthcare businesses that may utilize the laboratory application described herein. Several exemplary sites 60 are shown. Each site 60 may be associated with a health care organization, facility, or business, such as a physician's office, laboratory, health plan, hospital, etc. The individual sites 60 may be operable to share various types of information with each other, including laboratory information, such as laboratory requisitions, test results, etc. It is noted that the sites 60 shown in FIG. 2 represent typical types of businesses found in a typical Health Data Network, and any of various other organizations may be present in other embodiments of a Health Data Network. Also, any number of organizations or businesses may be connected to the HDN.

[0066] As shown, each site 60 may utilize a computer system 62 and may also utilize one or more databases 64. Among other types of information, a database 64 may store patient record information. The use of patient information may differ for the various sites. For example, Physician's Office A (site 60B) may primarily use the patient records to view and update clinical information regarding patients' medical history, while the Health Plan (site 60D) may primarily use the patient records to manage insurance information for the respective patients.

[0067] In various embodiments, the information used by the various sites 60 may be stored at and retrieved from various locations. For example, information regarding a particular patient may be stored in the database 64E at site 60E, and the application running on computer system 62B at site 60B may be operable to retrieve the record from this database. As another example, the record may be stored in a database not specifically associated with any site 60. For example, if a person at site 60B creates a record, the record may be stored in a central database that stores patient record information for the various HDN Businesses.

[0068] In one embodiment, the computer systems associated with the various HDN Businesses may interface with a middleware server that facilitates the retrieval and update of patient records. For example, in response to a physician clerk's request to lookup a record for a patient at site 62B, an application running on computer system 62B may request the middleware server to retrieve any existing records for the patient, e.g., by specifying one or more identifiers associated with the patient, such as the patient's name, SSN, etc.

[0069] The middleware server may then retrieve the record, e.g., from a database at one of the sites 60 or from another database. In various embodiments, the middleware server may retrieve information in any of various ways.

[0070]FIGS. 3 and 4

[0071]FIG. 3 illustrates one embodiment of a system employing a middleware server to facilitate the integration of healthcare information. It is noted, however, that any of various systems or architectures may be used to retrieve and store healthcare information, and FIG. 3 is exemplary only. FIG. 3 illustrates a client application 100 that interfaces with a Client Object Server 110. For example, the client application 100 may be an application that a clerk at Physician's Office A uses to submit laboratory orders for patients. The Client Object Server 110 with which the client application 100 interfaces may perform the functions of the middleware server described above. The Client Object Server 110 preferably provides a single standard interface for all of the various client applications running on computer systems 62. The Client Object Server 110 preferably provides an API related to the laboratory orders which client applications 100 may use to submit lab orders, retrieve lab results, etc., as described below.

[0072]FIG. 4 illustrates a more detailed system based on the system of FIG. 3. FIG. 4 illustrates the electronic routing of laboratory orders and results. As shown, a plurality of caregiver offices 104 may execute GUI client applications 100. In some embodiments the GUI client applications may interface with a Patient Management System 102, e.g., in order to lookup patient records stored locally. Each GUI client application 100 may be used to enter laboratory requisition information, as described in detail below. Once the requisition information has been entered, the information may be transmitted electronically to a middleware server referred to herein as a “client object server (COS)” 110. The COS server 110 may then interface with other laboratory systems to transmit the lab orders and receive the lab results. The COS server may then route the orders back to the originating caregiver's office (or elsewhere as specified in the requisition information entered by the user).

[0073]FIG. 3 illustrates a client application 100 that interfaces with a client object server (COS) 110. The client application may be any of various types of computer processes, such as an application that a user interacts with, an application for performing bulk data loading, a communication process associated with another computer system, etc.

[0074] The FIG. 3 framework enables a client application to interact with distributed relational databases using a software object model. For example, an application dealing with customer invoices may request a “customer invoice object” from the client object server 110, in order to work with the customer invoice in terms of a software object, such as a C++ or Java object-oriented programming style object. The data for the customer invoice object may be stored in separate tables within a database, or may even be stored in separate databases. The client object server 110 is responsible for managing the retrieval and storage of object data from/to the appropriate locations. In other words, the FIG. 3 framework enables client application logic to be written independently of the data tier(s), and enables data tier(s) to change without requiring client applications to be re-written.

[0075] Modem distributed applications often utilize data stored in complex relational models. Enabling client applications to work with the data without requiring knowledge of the complex data model may greatly simplify application programming. Also, data integrity may be increased. For example, when data is added to one table, the data model may specify that a second table should also be updated to reflect the change. However, client application programmers may not know of the need to update the second table, or may forget to do so, resulting in data integrity.

[0076]FIG. 3 also illustrates an object dictionary 120. The client object server 110 interfaces with the object dictionary 120 to dynamically determine the data location(s), layout, and retrieval/storage methods. The object dictionary comprises metadata information regarding the data location(s), layout, and retrieval/storage methods for each object that client applications may request from the client object server. For example, the object dictionary may comprise information regarding a customer invoice object, as in the example above. The types of objects that may be defined and managed by the client object server is of course unlimited, and may depend on the purpose of a particular system or application. For example, a healthcare system may define objects representing patients, healthcare providers, etc. The object definitions may be dynamically changed by changing the object dictionary metadata information.

[0077] For more information on the interaction of the client object server with the object dictionary and for information on object lifecycle, please refer to the documentation incorporated by reference.

[0078] In one embodiment, information is passed between the client application and the client object server via CORBA sequences, e.g., as structured name/value pairs enabling the construction of an “object” on the client-side. Advantageously, this enables client applications to utilize object-oriented style programming without requiring true individual objects, e.g. CORBA objects, to be instantiated and passed to each client application, which could lead to scalability problems for a system with a large number of client applications that communicate with the client object server.

[0079] As shown in FIG. 3, the client object server 110 may interface with multiple service provider modules 130. Each service provider module 130 may provide a computing service or interact with another computer system. For example, FIG. 3 illustrates a service provider 130B that interacts with an object broker data server 140, such as the object broker data server described in the above-incorporated documentation. As other examples, a service provider may interact with a file system, a service provider may provide TCP/IP communication abilities, etc. Service providers may also be specific to a particular system or application. For example, an “eligibility” service provider may enable healthcare applications to determine the healthcare insurance eligibility information for a particular patient.

[0080] Thus, service providers 130 may add multi-tier aspects to the FIG. 3 framework. The client object server 110, together with the object dictionary 120, may enable client applications to utilize the respective service resources in an object-oriented style, without requiring client applications to possess knowledge of the service implementations. For example, a healthcare application may connect to an external healthcare payer system via an eligibility service provider and query the insurance eligibility status for an individual, using object-oriented methods as described above.

[0081] Each service provider may communicate with the client object server via CORBA sequences, similarly as described above, and may communicate with its respective resource in any way appropriate. For example, a service provider may interface with a database resource using a database communication protocol.

[0082] Service providers are preferably implemented so that new service providers may easily be incorporated into the framework. In one embodiment, the client object server communicates with each service provider via a common CORBA interface. Thus, a new service provider may be added by simply implementing this interface, as appropriate for the respective resource.

[0083]FIG. 5

[0084]FIG. 5 is a flowchart diagram illustrating one embodiment of a method for electronically sending lab requisitions to laboratories and electronically receiving lab results. In step 200, a user requests to initiate a requisition. An exemplary user interface for entering lab requisition information is described below. In step 202, user information specifying the requisition is received, such as patient information, billing information, test code information, etc.

[0085] In step 204, the requisition information is transmitted to a middleware server, such as the COS server 110 described above. In one embodiment, the information may be stored temporarily and batched later, e.g., when a user requests all requisitions to be batched.

[0086] In step 206, the middleware server may transmit the requisition information to one or more laboratories specified in the requisition. As shown in the system of FIG. 4, one or more intermediate servers may be involved in transmitting the requisition information.

[0087] Steps 208-216 may be performed for each lab specified in the requisition. In step 208, the lab receives the appropriate specimens corresponding to the requsition, i.e., the specimens upon which to perform the specified tests. The specimens are typically delivered to the lab by a courier. At the time the requisition information is entered in step 202, the system preferably prints labels to facilitate the proper handling and delivery of the specimens.

[0088] In step 210, the lab performs the test(s) specified by the requisition on the specimen(s).

[0089] In step 212, results of the tests performed may be entered into a laboratory information system for the lab. The middleware server (or an intermediate server) preferably interfaces with the laboratory information system and receives the lab results in step 214.

[0090] In step 216, the middleware server then routes the lab results to the appropriate caregivers, which may be the caregiver that initiated the requisition and/or another caregiver specified in the requsition information.

[0091] Laboratory Orders and Results Application

[0092] The remainder of this disclosure describes and illustrates one particular laboratory application that enables various healthcare sites, such as physician offices or hospitals, to connect to clinical laboratories, e.g., to electronically place lab orders and receive lab results.

[0093] After the user has successfully logged on to the lab orders and results system, the main window appears, as shown in FIG. 6. In addition to standard user interface window components, the system main window has several application-specific components, including drop-down menus, an open items list, a desktop area, and a status bar.

[0094] Drop-down menus: The menu bar, located across the top of the system main window, provides access to all functions needed to use and maintain the system. Various menu items are described below.

[0095] Open Items list: The Open Items list, located on the left side of the system window, shows all items that are open. As the user works with various items, such as lab requisitions, patient records, etc., the items appear in the Open Items list. This feature allows the user to switch back and forth between different items without having to close the one the user is currently working on. FIG. 7 illustrates an exemplary Open Items list. In this illustration, the following items are open: two requisitions under the Order section, two patient records under the Patient section, and one patient group under the Report Group section. When the user log on to the system, the default item in the Open Items list is Main Menu. At the bottom of the list, there is a horizontal scroll bar that lets the user expand the view. To view an item from the Open Items list, the icon next to the item is clicked. The dark box around the item indicates that this is the item currently displayed on the system desktop.

[0096] Desktop: The desktop area, the large area located on the right side of the window, is where all screens of the application appear. When the application first opens, the system desktop is occupied by the Main Menu desktop menu, as shown in FIG. 6. This desktop menu provides a graphic means of accessing the most frequently used functions of the application.

[0097] Status bar: The status bar, located at the bottom of the desktop area, has two message panels. On the left side is the log on status, which displays the username used to log on at the workstation and the name of the active Health Data Network (HDN) Business. In the example of FIG. 6, the user doc4 is logged on at the workstation and Kennestone Hospital is the active HDN Business. On the right side is the lab results status, which displays the number of lab results that have not been viewed, i.e., new results electronically received from various labs but not yet reviewed, and the number of those results that are abnormal.

[0098] Functional Architecture

[0099] In one embodiment the system includes the following functional modules: Orders, Results, Patients, User, and Admin. Each of these modules is described below.

[0100] Orders Module

[0101] In one embodiment, there are twelve basic functions to the Orders module of the system:

[0102] Create Standard Requisition

[0103] Create Future Requisition

[0104] Access Requisitions

[0105] Manifest

[0106] ABN Form

[0107] Requisition Summary Report

[0108] Find Test Codes

[0109] Create Test Code

[0110] ICD-9 Codes

[0111] Lookup Labs

[0112] Manage Test Groups

[0113] Test Group Listing

[0114] These functions may be accessed from the Orders drop-down menu, as shown in FIG. 8 or from the Orders desktop menu, as shown in FIG. 9. The Orders functions pertain to creating and managing lab orders. The Orders functions are described below.

[0115] Orders: Create Standard Requisition

[0116] The user creates a “standard” requisition when the patient is on site and a specimen can be obtained right away. Once the requisition is completed, it can be sent to the lab. When the user creates a standard requisition, a requisition number may automatically be generated by the system. If the user's system is configured for entering manual requisition numbers, the system may also generate a requisition number every time the user creates a new requisition, but the user has the option of changing the requisition number.

[0117] The Create Standard Requisition menu option enables the user to:

[0118] Create a standard requisition for an existing patient.

[0119] Create a standard requisition for a new patient.

[0120] Print or preview the requisition.

[0121] Delete the requisition.

[0122] Each standard requisition is divided into four pages of information as shown in the following table: Page Name Includes . . . General Bill Type, patient demographics, and guarantor Billing Lab, primary care and referring physicians, ordering client information, collection date and time, and insurance Test Codes Diagnosis and test codes Additional Info Specimen information, lab instructions, comments, and a “Copy To” list.

[0123]FIG. 10 illustrates the General page of the Requisition window. Each page may be accessed by clicking on the appropriate tab at the top of the window.

[0124] Creating a Requisition

[0125]FIG. 11 is a flowchart diagram illustrating one embodiment of a method for creating a standard requisition.

[0126] In step 300 a Requisition window is displayed. The Requisition window includes fields for receiving user input specifying requisition information. In one embodiment, the Requisition window includes tabs for accessing a General page, a Billing page, a Test Codes page, and an Additional Info page, as described above.

[0127] In step 302 user input specifying a patient is received. For example, FIG. 12 illustrates a Finding a Patient window. The patient may be found by various identifiers, such as the name or social security number, or a recently viewed patient may be chosen. If a requisition is to be created for a patient who does not yet have a patient record, then the user may create a new patient record. In one embodiment, the Finding a Patient window appears automatically in response to a request to create a requisition, before the Requisition window is displayed in step 300.

[0128] In step 304, the record for the specified patient is received, and the record information is used to populate patient information fields of the Requisition window. In one embodiment, the system may be operable to maintain a Global Master Patient Index (GMPI) that integrates patient record information for multiple Health Data Network Businesses. Thus, this GMPI information may be used in retrieving the appropriate patient record.

[0129] In step 306, user input specifying general requisition information is received, such as contact information for the patient, guarantor information, etc. FIG. 10 illustrates an exemplary user interface for receiving this general information, i.e., the General page of the Requisition window displayed in step 300.

[0130] The FIG. 10 user interface also includes a field for specifying a Bill type, such as client, patient, or third party. If a requisition was previously created for the specified patient, relative information from that requisition, such as the Bill Type, also populates the appropriate fields. Otherwise, the remaining fields are populated with the default values.

[0131] In step 308, user input specifying billing information for the requisition is received. FIG. 13 illustrates an exemplary user interface for receiving this billing information, i.e., the Billing page of the Requisition window displayed in step 300. In one embodiment, when the user moves from the General page to another page, such as the Billing page, any data the user has entered in the patient information fields is automatically saved in the patient's record. A message may appear, advising the user that all requisitions will now use the new patient information. In one embodiment, the user may be able to choose whether or not to modify the patient record in this way. It is noted that the fields included in the user interface that is displayed in step 308 may depend on the Bill Type chosen by the user.

[0132] In step 310, user input specifying diagnosis codes for the requisition is received. FIG. 14 illustrates an exemplary user interface for receiving this diagnosis code information, i.e., the Test Codes page of the Requisition window displayed in step 300. The user may enter a list of diagnosis codes, such as ICD-9 codes that specify the caregiver's diagnosis for the patient.

[0133] In step 312, user input specifying test codes for the requisition is received. FIG. 14 illustrates an exemplary user interface for receiving this test code information, i.e., the Test Codes page of the Requisition window displayed in step 300. The user may enter a list of test codes specifying the desired lab tests to perform on the patient specimen(s).

[0134] In step 314, user input specifying a list of labs to whom to electronically send the requisition is received. In the preferred embodiment, the system is operable to send requisitions to a plurality of labs.

[0135] As shown in the user interface of FIG. 15, user input specifying other information for the requisition may also be received, such as lab instructions, information regarding the patient specimens collected, etc.

[0136] In step 316, the requisition is validated by the system, e.g., in response to receiving user input specifying that the user is done entering information. If there are errors in the information entered for the requisition, an error message may appear, and the user may be required to correct the errors.

[0137] In one embodiment, when the bill type chosen is Third Party and the patient insurance is for a Medicare payer and the user selected a test code that is not LCP-compliant or FDA-approved, the ABN Dialog box appears.

[0138] If the patient has already signed an ABN Form, the user selects Yes next to The Patient has signed an ABN Form. The Patient Acknowledgment of Non-Covered Services statement will print at the bottom of the requisition.

[0139] If the patient has not already signed an ABN Form, the user selects No next to The Patient has signed an ABN Form. If the patient is in the user's office and can sign an ABN Form, the user selects Yes next to Patient Is Here to Sign an ABN form. The Patient Acknowledgment of Non-Covered Services statement will print at the bottom of the requisition. The user should then have the patient sign the statement.

[0140] Otherwise, the user selects No next to Patient Is Here to Sign an ABN form. If there are other medically appropriate diagnosis codes in the patient's chart for this date of service, then the user may specify Yes, and the requisition window appears, allowing the user to click on the Test Codes page and select appropriate ICD-9 Diagnosis Codes for the selected tests. Otherwise, the user specifies No, and an ABN Warning appears.

[0141] In step 318, user input specifying a number of specimen labels to print may be specified, and the system may then print the specimen labels. The specimen labels may include information from the requisition that facilitates efficient handling of the specimen.

[0142] In step 320, the requisition information may be stored. The user may later use the Access Requisitions option of the Orders menu to select and electronically send the requisitions, e.g., by interfacing with the middleware COS server 110 illustrated in FIG. 3.

[0143] Requisition Window Fields

[0144] The following sections describe fields for the four pages of the exemplary Requisition Window described above (i.e., the General page, Billing page, Test Codes page, and Additional Info page).

[0145] The procedure for entering the information on the pages of the Requisition window is determined by the bill type selected on the General page. In one embodiment, there are three possible bill types, as shown in the following table: Bill Type The lab will bill . . . Client The client (provider or physician) ordering the tests Patient The patient's guarantor Third Party The patient's insurance

[0146] If the user has previously created a requisition for the selected patient, the Bill Type field may be populated with the selection made on the last requisition. If the user has not previously created a requisition for the selected patient, the field may be populated with the default value for the HDN Business the user is logged into.

[0147] A bill type of Client means that the client will be billed for services rendered. No additional billing information will be required.

[0148] A bill type of Patient means that the patient will be billed for services rendered. The user will need to enter guarantor information for the patient on the Billing page.

[0149] A bill type of Third Party means that an insurer will be billed for services rendered. The user will need to enter insured and payer information on the Billing page.

[0150] Requisition—General Page

[0151] The General page includes basic patient demographic information, as well as a field for the Bill Type. As shown in FIG. 10, The following fields may be included on the General page: Account # (The patient's account number); Address; Age; Birth Date; City; First Name; Home Phone; Last Name; Middle Name; Operator ID (The identifier for the operator creating the requisition); Sex; SSN; State; Zip.

[0152] For various of the above fields, if the user selects an existing patient and the information exists in their record, the field may be automatically populated. Changes made to the field may also change the patient's existing record.

[0153] The General page also includes a set of fields for entering Guarantor information, e.g., for the name and contact information for the Guarantor. The fields are only active if the value in the Bill Type field is Patient. If the user has previously created requisitions for the selected patient where the Bill Type was set to Patient, the guarantor information from the last requisition may populate the fields. If the user has not previously created requisitions for the selected patient or if this is a new patient, the fields are blank. If the user selects an existing guarantor and the information exists in their record, the fields are automatically populated.

[0154] Requisition—Billing Page

[0155] The Billing page (see FIG. 13) includes a set of fields for entering patient insurance information. These fields are only active if the value in the Bill Type field on the General page is set to Third Party. If the user has previously created requisitions for the selected patient, the insurance information from the last requisition populates the fields. If the user has not previously created requisitions for the selected patient, these fields are blank.

[0156] Insured information fields—The Billing page may include a set of fields for information related to the Insured, such as: address, city, first name, last name, phone number, relationship (for specifying the patient's relationship to the insured), etc.

[0157] Payer information fields—The Billing page may include a set of fields for information related to the Payer, such as: address, city, group number (the group number of the policy for the selected patient insurance), insurance code (The identifying code for the payer), member/policy number (The member or policy number for the selected patient insurance), name (he name of the payer for the selected patient insurance), state, zip, etc.

[0158] Order information fields—The Billing page may also include selected order information, including Performing Lab, Requisition Status, Ordering Client, Client ID, and Referring Physician. If the user has previously created requisitions for the selected patient, the order information from the last requisition may populate the fields. If the user has not previously created requisitions for the selected patient, the fields are blank.

[0159] Before a physician or provider can order a test, they must be setup in the system. The Health Data Network (HDN) Business that is associated with the physician or provider must also be setup to do electronic transactions. Otherwise, when the user tries to find the name of the ordering physician, the system will not be able to locate it and a pop up window with the message “No records were found” will appear.

[0160] The ordering physician may or may not have a Client ID number. If the physician has a Client ID number, the system automatically displays that number in the Ordering Physician Client ID field. Otherwise, it displays the HDN Business Client ID. An administrator may be responsible for setting up the links between providers and caregivers and assigning Client IDs to those caregivers. These assignments are made through the Manage Security/HDN Businesses and Manage Businesses/Providers functions, which are accessed through the Admin menu, as described below.

[0161] The system may automatically generate and assign a unique requisition number to each new requisition. If the user's system is configured for entering manual requisition numbers, the user has the option of changing the requisition number. This requisition number appears displayed on the title bar of the patient window.

[0162] The billing information fields may include the following fields, as shown in FIG. 13: Field Description Client ID The ordering physician lab client identifier. If the ordering physician does not have a specific lab client ID, the default client ID of the active HDN Business is used. Collection The date and time when the sample was collected. Date/Time Ordering Client The physician ordering the tests. The physician must be a lab client or associated with a provider who is a lab client. If the patient's Primary Care Physician is a lab client, this field is populated with that physician's name. Performing Lab The lab that will perform the tests. This field is automatically populated with the default lab set up for the active HDN Business. Primary Care The Primary Care Physician for the patient. If the user Physician selects a client physician as the patient's Primary Care Physician, that physician will be used as the default Ordering and Referring physician on the Order Info page. Referring The physician that referred the patient to the ordering Physician physician. The ordering physician is automatically used for this field. The referring physician does not have to be a client of the lab. Requisition The number assigned by the system for the requisition. Number Requisition The status of the requisition. The default status for a Status standard requisition is “entered”. The default status for a future requisition is “inactive”. STAT Checking this field indicates that the ordering physician wants STAT processing of this order

[0163] Requisition—Test Codes Page

[0164] The Test Codes page (see FIG. 14) includes fields for entering laboratory test code information for the requisition, such as ICD-9 diagnosis codes and test codes.

[0165] ICD-9 stands for International Classification of Diseases version 9. ICD-9 coding is recommended for use in all clinical settings and is required for reporting diagnoses and diseases to all U.S. Public Health Service and Health Care Financing Administration programs. The user can retrieve ICD-9 and test codes from the user's Preferred List of codes by selecting Preferred List from the field control menu located next to the each input field.

[0166] The ICD-9 code list may include the following columns, as shown in FIG. 14: Description The description of the ICD-9 Diagnosis Code ICD-9 Code The ICD-9 Diagnosis Code User Description A user-defined description for the ICD-9 Diagnosis Code

[0167] Test codes are used to specify what tests to perform on a patient. When the user prints or previews a requisition, the user will see the tests codes listed under the heading PROFILE/TESTS.

[0168] If a selected test code includes Ask-at-Order-Entry (AOE) questions, the first question in a series appears on the screen. The user may then answer the question and click Continue. Questions continue to appear until the user has answered them all. After the last question is answered, the Test Codes page appears.

[0169] If the user selects a PAP test, the PAP Information window appears. The user enters the appropriate information in each of the fields.

[0170] If the user attempts to add a test code that is already on the list, the Duplicate Found dialog box appears.

[0171] The test code list may include the following columns, as shown in FIG. 14: Description The description of the test code Expiration Date The expiration date of the test code Special Test Indicates whether or not the specimen for the test code requires special handling Test Code The test code

[0172] Requisition—Additional Info Page

[0173] The Additional Info page (see FIG. 15) includes fields for entering additional information regarding the requisition. The test codes the user selects on the Test Codes page, the Bill Type setting on the General page and the type of the active HDN Business (e.g., “physician practice” or “hospital”) determines which of these fields is required. For example, when the user orders a test that requires 24 hour urine samples, the user is asked a series of questions such as the patient's height, weight and urine volume. In this case, the user would complete these fields: Lab Instructions, Urine Volume ML, and Urine Hrs, and any other information relevant to the patient or test being performed.

[0174] The Additional Info page may include the following fields, as shown in FIG. 15: Field Description Fasting Hrs The number of hours the patient fasted before the specimen was collected Hospital ID If the active HDN Business is a hospital, this is the hospital's identifier Lab These are specific instructions from the ordering Instructions physician to the lab for tests ordered Lab Reference The lab reference Location If the active HDN Business is a hospital and the patient has been admitted, this is the patient's location Phone in Selecting this field indicates that the ordering physician Results wants the lab to phone in the results, as well as return them electronically. In this field, the user must enter the phone number that the user wants the lab to call Prepaid The amount the patient has prepaid for the tests Amount ordered Report This field is for any comments from the ordering Comments physician that need to accompany the tests ordered Room # If the active HDN Business is a hospital and the patient has been admitted, this is the patient's room number Send Copies to This is a list of physicians that should be copied on the results. All physicians on this list must be a lab client or associated with an HDN Business that is a lab client Shift If the active HDN Business is a hospital and the patient has been admitted, this is the shift which collected the specimen Urine Hrs This is the number of hours for urine specimens Urine This is the number of milliliters of urine collected for Volume ML the tests

[0175] Orders: Create Future Requisition

[0176] The Create Future Requisition menu option of the Orders menu enables the user to prepare a requisition before the patient arrives or the specimen is received. A future requisition can also be printed and given to a patient to take to a lab.

[0177] Future requisitions are stored in the system until the specimen is collected. When the user creates a future requisition, a requisition number is automatically generated by the system. If the user's system is configured for entering manual requisition numbers, the user has the option of changing the requisition number.

[0178] The distinction between standard and future requisition types exists to keep track of those requisitions whose specimens have not been collected yet. The system accomplishes this by assigning a different status to each type. When a standard requisition is created it has an Entered status. When a future requisition is entered its status is Inactive.

[0179] The Create Future Requisition menu option enables the user to:

[0180] Create a future requisition for an existing patient

[0181] Create a future requisition for a new patient

[0182] Print or preview the requisition

[0183] Delete the requisition

[0184] Activate the requisition, which tells the system that a future requisition can be sent to the lab for processing

[0185] Each future requisition is divided into four pages of information, similar to the four pages described above with reference to standard requisitions. The procedure for entering the information on these pages is determined by the bill type selected on the Patient page. There are three possible bill types: Client, Patient, and Third Party.

[0186] At the bottom of every page in the Create Future Requisition function there is a row of buttons which correspond to the following functions: Button Names Function Print Opens the Print dialog, allowing the user to print the requisition and specimen labels. Help Opens the help topic for the current active page. Delete Deletes the requisition. Activate Activates the requisition (changes the status from “inactive” to “entered”) so that it may be sent. <<Back Moves to the previous page of the requisition. Next >> Moves to the next page of the requisition. Save Saves the requisition. The user cannot save a requisition until all the required fields are complete. Close Closes the requisition.

[0187] Creating a future requisition follows a similar procedure as described above for creating standard requisitions. As needed, the user activates future requisitions through the Access Requisitions option of the Orders menu.

[0188] Orders: Access Requisitions

[0189] The Access Requisitions menu option of the Orders menu enables the user to keep track of all the requisitions generated from the user's office and their current status. From the Access Requisitions menu option the user can:

[0190] View a list of requisitions

[0191] View all details of a requisition

[0192] Modify a requisition

[0193] Print a list of requisitions

[0194] Print details of a requisition

[0195] Delete a requisition if it has not been sent to a lab

[0196] Send one or more requisitions

[0197] Send all requisitions

[0198] The user can find requisitions by using requisition information or by using patient information. Each method enables the user to use different parameters to narrow down the results of the user's search. For example, the user may want to generate a list of all the entered requisitions whose specimens were collected within a certain time period, or the user may want to obtain a list of all the requisitions that were ordered by a physician for a patient. Also, there may be times when the user needs to add more information to an existing requisition that has not been transmitted to a lab yet, as in the case where a doctor requests an additional test for a patient or the user needs to change information on the patient's insurance coverage. In both cases, the user would search for the requisition, make the required changes to it and then save it. A doctor may also decide to cancel a requisition, in which case, the user would delete that requisition because it is no longer needed.

[0199] From the General page, the user can find a requisition using one or more of the following search criteria: Requisition #; Requisition Status; Ordering Provider; Lab; Collection Date Range; and Stat Only. FIG. 16 illustrates the General page of the Access Requisitions window.

[0200] From the page labeled By Patient Info, the user can find a requisition using one or more of the following search criteria: Patient; Ordering Physician; Referring Physician; Bill Type; Client ID; and Anonymous Requisition.

[0201] The user can generate a list of requisitions stored in the system by specifying at least one of the search parameters in the Access Requisition window. Requisitions can be modified and/or deleted as long as they have not been sent to the lab for processing. The requisition status indicates whether a requisition has already been transmitted.

[0202] Orders: Manifest

[0203] The Manifest menu option of the Orders menu enables the user to generate a manifest manually for those cases where the original manifest may be misplaced or if the user just wants to have an extra copy of the manifest for the user's records. A manifest is used by the submitting client to verify that all specimens are accounted for. The manifest lists all the tests ordered on each requisition, and it provides a convenient means for both the courier, who picks up the specimens, and the receiving laboratory to verify that the correct number of specimens and requisitions is received.

[0204] The Manifest window is shown in FIG. 17. Clicking the Find Now button on the Manifest window without specifying any search criteria generates a listing of all requisitions with a ‘Transmitted’ status in the user's active HDN Business. The user can narrow down the results list by specifying one or more of the following search criteria: Stat Only; Inclusion; Sort Order; and Collection Date/Time Range.

[0205] The search results appear listed under the following column headings: Requisition No.; Patient Name; Patient Account #; Status; and Ordering Client. When the results of the user's search appear on the Manifest window, the user can selectively highlight those requisitions the user wants to include on the manifest. A manifest can be previewed or printed. The first page of the report is a header page that shows the name of the ordering provider and the search criteria that were used to generate the manifest. The rest of the report displays a list of all the requisitions in the manifest under the following column headings:

[0206] Control #

[0207] Pat. Account

[0208] Patient Name

[0209] Age

[0210] Sex

[0211] Hosp ID

[0212] Lab Ref.

[0213] Collection Date/Time

[0214] Urine Vol. & Hrs.

[0215] Test

[0216] Operator ID

[0217] Results Received

[0218] Orders: ABN Form

[0219] The ABN Form menu option enables the user to access an Advanced Beneficiary Notice (ABN) Form. An Advanced Beneficiary Notice is a printed statement that contains a list of tests not covered by the payer. By signing an ABN form, the patient or the insured accepts financial responsibility for those tests that are not covered by the payer. For example, Medicare has limited coverage. An ABN form is generated when the user enters information on the Requisition Test Codes page. If the test code the user enters is for a limited coverage test and the diagnosis code is not approved to cover that test, the system prompts the user to answer questions pertaining to the ABN and have the patient sign the statement that is printed at the bottom of the requisition.

[0220] The only search criteria required to generate this form is the payer or insurance company name. An optional header page can be included as the first page in the report showing:

[0221] Date and time when the form is printed

[0222] Name of the user generating the form

[0223] Comment line

[0224] Search criteria used to generate the form

[0225] Once the ABN form is complete and signed by the patient, a copy of it can be sent to the lab along with the accompanying requisition and specimen.

[0226]FIG. 18 illustrates the ABN Form window. A print preview of the ABN form may be displayed. FIG. 19 illustrates the ABN Form Print Preview window.

[0227] Orders: Requisition Summary Report

[0228] The Requisition Summary Report menu option of the Orders menu enables the user to generate a list of requisitions for any date range, patient, ordering physician and requisition status. The user can also get a listing of all requisitions by just running the report without specifying any of these search parameters. However, without specifying some search criteria the report may be very large.

[0229] The Report page, shown in FIG. 20, lets the user specify a header page as a configurable option. The header pages shows:

[0230] Date and time of the report

[0231] Name of the user running the report

[0232] Comment line

[0233] Search criteria used to generate the report

[0234] The Format Options page lets the user specify how the user want the report to be sorted. The report can be sorted by:

[0235] Patient Last Name

[0236] Requisition Number

[0237] Patient Account Number

[0238] The Requisition Summary Report can be either previewed or printed. FIG. 21 illustrates the Requisition Summary Print Preview window. The report is printed and displayed in landscape mode with the following column headings:

[0239] Control # (same as Requisition #)

[0240] Status

[0241] Pat. Account

[0242] Patient Name

[0243] Age

[0244] Sex

[0245] Hospital ID

[0246] Lab Reference

[0247] Collection Date/Time

[0248] Test

[0249] Description

[0250] In addition, the system prints each ordering physician's full name and Client ID at the beginning of each page in the report.

[0251] Orders: Find Test Codes

[0252] The Find Test Codes menu option of the Orders menu allows the user to locate test codes for labs. When selected, the Find Test Codes window appears, as shown in FIG. 22. The user can enter the search criteria needed to best locate the test code the user wants to find and click Find Now to perform the search. The results appear in the list at the bottom of the window. The user can then locate and select the test code(s) the user wants to use. The user can also add test codes to a Preferred List of Test Codes.

[0253] Orders: Create Test Code

[0254] The Create Test Code menu option of the Orders menu allows the user to create new test codes for labs. When selected, a blank Test Code Details window appears, as shown in FIG. 23, allowing the user to fill in the fields to create a new test code.

[0255] Orders: ICD-9 Codes

[0256] The ICD-9 Codes menu option of the Orders menu allows the user to locate ICD-9 codes. When selected, the Find ICD-9 Code window appears, as shown in FIG. 24. The user can enter the search criteria needed to best locate the ICD-9 code(s) the user wants to find and click Find Now to perform the search. The results appear in the list at the bottom of the window. The user can then locate and select the ICD-9(s) the user wants to use. The user can also add ICD-9 codes to a Preferred List of ICD-9 Codes.

[0257] Orders: Lookup Labs

[0258] The Lookup Labs menu option of the Orders menu allows the user to locate and select labs available for the user's use, e.g., to electronically send requisitions to the labs. When selected, the Lookup Labs window appears, as shown in FIG. 25. The user can click the Lab field control button and choose Select to display a list of available labs.

[0259] Orders: Manage Test Groups

[0260] The Manage Test Groups menu option of the Orders menu allows multiple tests to be grouped together for the purpose of ordering. Each test group is identified by a code and includes multiple tests. Being able to enter test group codes instead of individual test codes saves the user time and promotes accuracy when creating a requisition, e.g., by preventing erroneous test code from being entered and ensuring that required codes are not forgotten.

[0261] Test Groups also help the user simplify the task of creating requisitions by enabling the user to work with only those test codes that are specific to a group of patients in the user's practice. For example, the tests performed in an allergy/immunology practice will more than likely differ from those performed at an office specializing in cardiovascular diseases. Also, there may be multiple physicians in a practice, and each physician may handle specific types of patients who require different types of tests.

[0262] When the user chooses Manage Test Groups from the Orders menu, the Test Group Management window appears, as shown in FIG. 26. From this window, the user can:

[0263] List all test groups

[0264] List all the test codes in a test group

[0265] Create New test groups

[0266] Add a new code to a test group

[0267] View/Modify details in a test group

[0268] Remove a test group

[0269] Remove a test from a test group

[0270] Print a list of all test groups

[0271] Print details on a specific test group

[0272] Orders: Test Group Listing

[0273] The Test Group Listing menu option of the Orders menu allows the user to preview or print a list of all the test groups for each provider that are created through the Manage Test Groups function. The items on the list appear sorted in alphabetical order. A header page is a configurable option. The header pages shows:

[0274] Date and time of the report

[0275] Name of the user running the report

[0276] Comment line

[0277] Search criteria used to generate the report

[0278]FIG. 27 illustrates the Test Group Listing window. Results Module

[0279] In on embodiment, there are six basic functions to the Results module of the system:

[0280] View Results

[0281] View Result Reports

[0282] Cumulative Report

[0283] Results Summary Report

[0284] Manage Report Groups

[0285] Report Group Listing

[0286] These functions may be accessed through the Results drop-down menu, as shown in FIG. 28, or the Results desktop menu (not shown). The Results functions pertain to reviewing and managing lab results. The Results finctions are described below.

[0287] Results: View Results

[0288] The View Results menu option of the Results menu provides flexible, on-demand reporting capability for current and historical test data. This reporting feature enables a physician to track a patient's progress over a period of time. The View Results window is shown in FIG. 29. This window enables the user to generate a listing of results based on the following search criteria: Patient Account; Patient; Analyte Codes; Report Codes; Profile Codes; Collection Date Range; and Result Date Range. The user may be required to enter

[0289] The Format Options page of the View Results window lets the user specify how the user want the results to be sorted. The report can be sorted in reverse chronological order or in chronological order.

[0290] The Results Report can be previewed or printed. The report may be printed and displayed in landscape mode with the following column headings:

[0291] Collection Date/Time

[0292] Requisition #

[0293] Test/Description

[0294] Result

[0295] Normal Range

[0296] Units

[0297] Specimen Type

[0298] Reported Date/Time

[0299] A header page is a configurable option for a Results Report. The header page shows:

[0300] Date and time of the report

[0301] Name of the user running the report

[0302] Comment line

[0303] Search criteria used to generate the report

[0304] In addition, the system prints detailed information on the selected patient at the top left hand comer of the report which includes patient name, patient account, patient age and sex. FIG. 30 illustrates a Results Report Print Preview Window.

[0305] Results: View Result Reports

[0306] As described above, the user interface windows of the application display a status message at the bottom right comer of the screen showing “Not Viewed Results” and “Abnormal Results”. This status message tells the user if any new test results have been electronically received. It also tells the user if any of those test results are abnormal.

[0307] The View Result Reports function enables the user to preview and print electronic reports of lab results. The user can use a variety of search criteria to narrow down the results of the user's search.

[0308]FIG. 31 illustrates the General page of the Find Result Reports window. From the General page the user can specify one or more of the following:

[0309] Patient

[0310] Result Type

[0311] Performing Lab

[0312] Performing Lab Type

[0316]FIG. 32 illustrates the By Requisition page of the Find Result Reports window. From the By Requisition page the user can specify one or more of the following:

[0317] Requisition #

[0318] Ordering Physician

[0319] Referring Physician

[0320] Ordering Provider (this field is populated by the system with the name of the

[0321] currently active HDN Business)

[0322] Result Status

[0323] The results of the user's search are displayed under the following column headings:

[0324] Req. #

[0325] Acc. #

[0326] Patient Name

[0327] Collection Date

[0328] Status

[0329] Abnormal

[0330] Result Date

[0331] Ordering Physician Name

[0332] Provider

[0333] Lab

[0334] Viewed

[0335] Once a list of result reports appears on the screen, the user can select one or more of the results to view or print them, e.g., by highlighting the desired result(s) and clicking the View/Print Result button. When the user clicks the View/Print Result button, a Print Options window appears. This is where the user specifies whether the report should show abnormal high/abnormal low flags next to each result and whether the user wants to preview or print the report.

[0336] Results: Cumulative Report

[0337] The Cumulative Report menu option of the Results menu allows the user to review and print analyte results for a patient over a specified period of time. This reporting tool provides a physician the ability to examine a patient's progress over a period of time and simplifies the collecting, organizing and filing of test results for a patient or patients. The main difference between Cumulative Reports and View Results Reports is in the way information is displayed. In a Cumulative Report the results for a single analyte appear listed horizontally over several date/time column headings. Also a Cumulative Report does not show requisition numbers or additional information on a test such as normal range, units and specimen type.

[0338]FIG. 33 illustrates the Report page Cumulative Reports window. The user can specify the following criteria to narrow down the results of the search:

[0339] Date Range

[0340] Patient

[0341] Patient Group

[0342] Shift

[0343] Location

[0344] Ordering Physician

[0345] Report Group

[0346]FIG. 34 illustrates the Format Options page of the Cumulative Report window. In the Format Options page, the user can select the following options to display a Cumulative report:

[0347] Display Date/Time horizontally and Analyte Code vertically or vice versa

[0348] Display results in chronological order or reverse chronological order

[0349] Title (An optional free text field where the user can enter a report title)

[0350]FIG. 35 illustrates the Print Options page of the Cumulative Report window. In the Print Options page, the user specifies what additional supplemental information to include in the report. The user may select from the following three sections to include in the report.

[0351] Section I—Results Summary

[0352] Section II—Text and Notes

[0353] Section III—Performing Laboratories

[0354] The Results Summary section shows a listing of analyte results for a patient over a period of time. This is the most important component in a cumulative report. Results appear under their corresponding collection date/time column headings. Abnormal results are flagged with an H for high or L for Low.

[0355] The Text and Notes section of the report displays miscellaneous notes and remarks associated with test results. Text and notes can originate from report comments the user enters on the Additional Info page of a requisition or from an authorized user at the lab such as a lab director, medical technologist, pathologist or microbiologist. Non-numeric results such as “positive” or “abnormal” appear in the Text and Notes section. For example, if the results of a CBC test reveal a low red blood cell count, the lab technician may include a message along with the results such as: “R/O anemia. A complete blood count is used as a screening test for various states such as anemia, leukemia and inflammatory disease”.

[0356] The Performing Laboratories section lists the names and addresses of all the laboratories from which the test results were obtained.

[0357] After selecting the report search criteria, format options and print options, the results can be previewed or printed. When the results are previewed, an Analyte Result window appears, as shown in FIG. 36. Results are displayed one patient at a time. The top part of the display shows a heading with the patient's name, date of birth, sex and date range. Below the heading are the results for each analyte displayed over a period of time. The bottom part of the display contains the following set of buttons: Graph This button displays analyte results in a graph. The graph can be previewed and printed. Annotate This button opens a free text window where the user can enter comments. Comments can be viewed, modified and deleted. View Message This button displays a window with text messages that originate from TopLab. If there are no messages from TopLab, the message results window box appears empty. View Detail This button displays an Analyte Result Detail window that shows detailed information on the analyte result selected. Print Report This button prints the Analyte Result report that appears on the screen. <<Back This button displays the results of the previous patient. Next>> This button displays the results of the next patient. Close This button closes the Analyte Result window.

[0358] Results: Results Summary Report

[0359] The Results Summary Report menu option of the Results menu allows the user to generate a multiple patient report designed to present a one time summary of any results received that meet a certain criteria. FIG. 37 illustrates the Results Summary Report window. The user can customize the search criteria to produce only the results that best meet the user's practice requirements. For example, the user can generate a listing of all the patients who had abnormal or high HDL cholesterol readings over a period of time.

[0360] The user can specify the following criteria to narrow down the results of the user's search:

[0361] Date Range (dates of the first and last results to include in the report)

[0362] Patient (a list of patients whose to include in the report.)

[0363] Patient Group (a list of patient groups whose results to include in the report.)

[0364] Shift (the shift that collected the specimen for the results to be included in the report)

[0365] Location (the location where the specimen was collected for the results to include in the report.)

[0366] Ordering Physician (a list of ordering physicians of the requisitions corresponding to the results to include in the report.)

[0367] Report Group (a list of report groups to include in the report)

[0368] Results are printed per patient. The selection of analytes for the report is done using the report groups. A header page is a configurable option. The header pages shows:

[0369] Date and time of the report

[0370] Name of the user running the report

[0371] Comment line

[0372] Search criteria used to generate the report

[0373]FIG. 38 illustrates a Results Summary Report Print Preview window.

[0374] In the Format Options page of the Results Summary Report window, the user can select the following options to display a Results Summary report:

[0375] Format Style (Tabular or List)

[0376] Clinical Status (Normal, Abnormal or Both)

[0377] Sort Order (Patient Name or Account Number)

[0378] Title (An optional free text field where the user can specify a report title)

[0379] Results: Manage Report Groups

[0380] Report Groups are user-defined collections of analyte codes, report codes and profile codes. The Manage Report Groups menu option of the Results menu allows the user to create and maintain these report groups.

[0381] Report Groups are used to generate Results Summary Reports and Cumulative Reports. Information obtained from these reports can be used to schedule patient visits in advance, gather valuable statistical information, and identify trends in a patient population. A Results Summary Report is a listing of all the test results that meet a certain criteria such as date range, patient, patient group, shift, location, ordering physician and report group. A Cumulative Report allows the user to review and print information on any analyte or group of analytes, for a particular patient or group of patients over a specific time period.

[0382] When the user chooses Manage Report Groups from the Results menu, the Report Group Management window appears, as shown in FIG. 39. From this window, the user can:

[0383] List all report groups

[0384] List all the analyte codes in a report group

[0385] Create New report groups

[0386] Add a new code to a report group

[0387] View/Modify details in a report group

[0388] Remove a report group

[0389] Remove an analyte code from a report group.

[0390] Print a list of all report groups

[0391] Print details on a specific report group

[0392] The user can build a report group by selecting any combination of one or more profiles, report codes or analyte codes. Once a Report Group has been defined and given a name, it appears listed in the Report Group Management window. Regardless of what method the user uses to build a report group (by profile, report or analyte code), the report group always shows the individual analyte codes that make up the report group along with their individual name and description.

[0393] Results: Report Group Listing

[0394] The Report Group Listing menu option of the Results menu allows the user to preview or print a list of all the report groups for each provider that are created through the Manage Report Groups function. The items on the list appear sorted in alphabetical order. A header page is a configurable option. The header pages shows:

[0395] Date and time of the report

[0396] Name of the user running the report

[0397] Comment line

[0398] Search criteria used to generate the report

[0399]FIG. 40 illustrates the Report Group Listing window, and FIG. 41 illustrates a Report Group Listing Print Preview window.

[0400] Patients Module

[0401] In one embodiment, there are five basic functions to the Patients module of the system:

[0402] Patient Records

[0403] Link Duplicate Patient Records

[0404] Reconcile Duplicate Patient Records

[0405] Patient Group Listing

[0406] Manage Patient Groups These functions may be accessed through the Patients drop-down menu, as shown in FIG. 42, or the Patients desktop menu. The Patients functions pertain to managing patient records. The Patients functions are described below.

[0408] The Patient Records menu option of the Patients menu allows the user to:

[0409] Create new patient records

[0410] Find existing patient records

[0411] View details of existing patient records

[0412] Modify details of existing patient records

[0413] Print existing patient records

[0414] Each patient record may include the following types of information:

[0415] Demographics information, such as:

[0416] Account #

[0417] Patient's Name

[0418] Home address

[0419] Home, work, and fax phone numbers

[0420] General identification, such as Social Security Number and driver's license number

[0423] Religious information including religion, place of worship and religious contact

[0424] Name Aliases (other names by which the patient has been or is known)

[0425] Identifier information. The system allows the user to link to a single patient record multiple identifiers that the user's organization and other organizations use to track the patient record, such as chart number, record number, test number and account number. For example, one facility may use Medical Record Numbers (MRNs) to keep track of its patients while another facility may use Patient Identification Numbers (PIDs) for the same purpose.

[0426] Employment information, both past and present, including employer name, address, phone numbers, employment period and position.

[0427] Guarantor information, which lists the person(s) responsible for any medical procedures not covered by a payer or a third party. A guarantor can be any of the following:

[0428] the patient

[0429] a parent

[0430] the patient's spouse

[0431] the patient's employer

[0432] any other person financially responsible for the patient's medical expenses

[0433] Medical Data, which the user's office and other organizations maintain for a patient.

[0434] Insurance information, which includes insurance code, payer, insured name, policy/member number, and effective dates.

[0435] Documents, which is a list of all documents, such as X-rays, lab reports, and medical notes, etc., that have been added to the patient's file either through the user's organization or other organizations.

[0436] Contacts, which is a list of all persons who are contacts for the patient and includes the person's name, address, phone numbers and relationship to the patient.

[0437] Consent information, which indicates if there is a valid patient consent form on file for a particular patient record.

[0438] Orders, which lists all laboratory tests performed on a patient.

[0439] Result Reports, which lists the results of all laboratory tests performed on a patient.

[0440] Diagnosis Codes, which includes a patient's diagnosis codes and their description.

[0441] Patient information is used by many other modules in the system and is shared within the user's organization as well as other organizations participating in the care of the patient. Therefore, great care should be taken to maintain the accuracy and integrity of this information. The system includes various features for helping to maintain data integrity, as described below.

[0442] Assuming the user has the proper security clearance, the Patient Records function of the system allows the user to carry out the following within each patient record:

[0443] Enter and modify demographic information in a patient record

[0444] Add, modify and remove name aliases in a patient record

[0445] Add, modify and remove identifiers in a patient record

[0446] Add, modify and remove employment records in a patient record

[0447] Add, modify and remove guarantor information in a patient record

[0448] Add, modify and remove medical data in a patient record

[0449] Add, modify and remove insurance information in a patient record

[0453] Add, modify and remove lab orders from a patient record

[0454] View and print lab result reports in a patient record

[0455] Add and remove diagnosis codes in a patient record

[0456] Finding Patient Records:

[0457] Patient records may be looked up in various ways, including by name, by identifier, or by social security number. The user may also perform a “power search” to lookup patient records. FIG. 43 illustrates the Finding a Patient basic search window. This window may appear after selecting the Patient Records menu option from the Patients menu or in other contexts, such as in response to selecting Create Standard Requisition from the Orders menu.

[0458] In one embodiment, the system may be enabled to interface with a Practice Management System (PMS). If the user's system has a PMS interface and the user searched by Patient Account identifier type, the system may search the PMS first. If a record is not located in the user's PMS with the matching account identifier, the PMS Search dialog box appears. The patient index maintained by the system may then be searched for a matching record.

[0459] After performing a search, the search results appear in the Finding a Patient window, as shown in FIG. 44. The patient record of interest may then be selected, and the appropriate window appears. For example, if the Finding a Patient window was opened through the Create Standard Requisition or Create Future Requisition options of the Orders menu, the Requisition window appears with the General page active, as shown in FIG. 10. If the Finding a Patient window was opened through the Patient Records option of the Patient menu, the Patient Details window opens with Chart Page 1 active, as shown in FIG. 45. FIG. 43 illustrates Chart Page 2 of the Patient Details window.

[0460]FIG. 47 illustrates the Finding a Patient power search window, which may also be used to lookup patient records.

[0461] Working with Patient Records: Patient Name Aliases

This page may be used to edit or enter diagnosis code information for the patient.

[0485] Duplicate Patient Records and GMPI Overview

[0486] Because patient records are setup and maintained by multiple users at multiple facilities in the Health Data Network, it is possible that a patient will have multiple patient records. This can create problems when determining which record to maintain. Duplicate records can splinter clinical data and hinder access to patient information.

[0487] For this reason, the system implements a Global Master Patient Index (GMPI). The GMPI can link multiple records together for the same patient. Thus, the GMPI gathers patient information together under a single umbrella. In the preferred embodiment, GMPI functionality within the system includes:

[0488] Locating patient records

[0489] Locating duplicate records for a selected patient

[0490] Printing a selected patient record with all its duplicate patient records

[0491] Reconciling potential duplicate patient records found while searching and retrieving a patient's record

[0492] Final reconciliation (certification) of suspected duplicate patients records

[0493] Maintaining a persistent relationship between patient records in the GMPI

[0494] Maintaining a reconciliation audit trail

[0495] Patients: Link Duplicate Patient Records

[0496] The Link Duplicate Patient Records menu option of the Patients menu enables the user to link two patient records that are suspected of being duplicates of each other. When linking the records, one is designated as the lead record (also called a master record) and the other the trailer of the lead record. Once linked, if the user selects the trailing patient record, the lead patient record will be opened instead. The dialog box shown in FIG. 48 appears in order to notify the user that this has occurred.

[0497] The link established between the two records using the Link Duplicate Patient Records menu option may be referred to as a confirmed link. This confirmed link may then be certified, e.g., by a GMPI administrator.

[0498] When the user selects the Link Duplicate Patient Records menu option, the Create Link Between Patients window appears, as shown in FIG. 49. In the Patient A field, the user selects the first patient of the duplicate pair. In the Patient B field, the user selects the second patient of the duplicate pair. If the user wants Patient A to be the lead record, the user clicks Confirm B into A. If the user wants Patient B to be the master record of Patient A, the user clicks Confirm A into B. The Confirm Link Dialog Box then appears, as shown in FIG. 50. The user clicks Yes to confirm the link as described in the dialog box. A confirmed (directional) link between the records is then created, and the Created a Link dialog box appears.

[0499] An unresolved link occurs when a user is reconciling a duplicate pair through the Link Duplicate Patient Records and selects the “I do not know option”. In this case, the link status changes from an unconfirmed link to an unconfirmed unresolved link. This link status is not visible to the user, but it will appear in the Suspected Duplicate Log under the Unconfirmed Link column. If the user selects a patient record with an unresolved link during the reconciliation process, the first column of the reconciliation grid on the LINK row will display the unresolved link status. If the link has been reconciled with the “I do not know” option meaning it is an unresolved link, the user line will display the name of the user who carried out the reconciliation action. Unresolved links do not appear displayed on any of the application screens, but the GMPI system keeps track of them in an audit trail log that can be viewed or printed by administrators.

[0500] Patients: Reconcile Duplicate Patient Records

[0501] The Reconcile Duplicate Patient Records menu option of the Patients menu is used to provide official certification of patient record links. This function is typically used by administrators who are responsible for the oversight and maintenance of the Global Master Patient Index (GMPI).

[0502] When the user selects the Reconcile Duplicate Patient Records menu option, a list of patient records that have links to other records appears, as illustrated in the Finding a Patient with Links window (FIG. 51). As shown in FIG. 51, the system provides filters enabling the user to filter the patient records that appear in the list. For example, the filter may be based on the system time stamp: e.g., 24 hours, 48 hours, 72 hours, 7 days, 30 days, etc. Also, a custom filter may be applied. For example, the custom filter may enable the user to search for patient records by link status, such as Unconfirmed Link, Indirect Link, Confirmed Link, Confirmed Unlink, Certified Link, and All.

[0503] The Certified Link column indicates the number of certified links for the patient. The Confirmed Link column indicates the number of confirmed links for the patient. The Confirmed Unlink column indicates the number of confirmed unlinks (or denigrated links) for the patient. The Indirect Link column indicates the number of indirect links for the patient. The Unconfirmed Link column indicates the number of unconfirmed links for the patient.

[0504] Assuming the user has the proper security clearance, the Reconcile Duplicate Patient Records function of the system enables the user to:

[0505] Retrieve and View the selected patient record and all its potential duplicates. The selected patient's demographics along with all its links appear in columnar format.

[0506] View a graphical representation of the selected patient record and all its potential duplicates.

[0507] Print demographics information for the selected patient record and its suspected duplicate records.

[0508] View details of the selected patient record or any of its duplicate records on the grid.

[0509] Reconcile a link between duplicate patient records. Reconciling a duplicate record pair involves one or more of the following tasks:

[0510] Denigrating a link between two records.

[0511] Certifying a confinned or unconfirmed link. This creates a certified link between two records.

[0512] Certifying a denigrated link

[0513] Denigrating a certified or confirmed link. When a certified or confirmed link is denigrated, it ceases to be directional.

[0514] Examine the Link Path of any potential duplicate records. This means that the user can select one of the duplicate records and make it the new selected patient record to view all of its links.

[0515] To find a patient record with links, the user chooses Reconcile Duplicate Patient Records from the Patients menu. The Finding a Patient with Links window appears, as shown in FIG. 51. The user may select a pre-defined filter from the drop-down list next to the Filter field. The user may apply a custom filter by clicking Custom. The Custom Filter window appears, as shown in FIG. 52. The user may then enter the filter criteria in the fields and click Apply to apply the filter and return to the Finding a Patient with Links window.

[0516] The result list appears, as shown in FIG. 51. To sort the list, the user can move the mouse pointer over the heading of the column to sort on and click. The search results list is sorted in ascending order using the selected column as the sort criteria.

[0517] To print the list, the user clicks Print List. FIG. 53 illustrates a Print Preview window.

[0518] To reconcile a patient record, the user highlights the desired record and clicks Continue. The Finding a Patient with Links table appears, as shown in FIG. 54. To reconcile duplicate patient records, the user highlights a Duplicate patient record to reconcile with the selected patient record and clicks Reconcile.

[0519] In response, the Reconcile Patient Duplicate dialog box appears, as shown in FIG. 55. The dialog box includes a statement at the top indicating which patient record is currently designated as the Potential Duplicate and which patient record is designated as the Selected Patient.

[0520] To make the Selected Patient the leader record of the Potential Duplicate, the user chooses “Yes. Make Selected Patient the new Master record”.

[0521] To make the Potential Duplicate the leader record of the Selected Patient, the user chooses “Yes. Make Duplicate # the new Master record”.

[0522] If the records are not duplicates, the user chooses “No. they are not duplicates”.

[0523] To certify the association between the Selected Patient and the Potential Duplicate, the use chooses “Certify the association between the Selected Patient and the Duplicate #.”

[0524] To denigrate the association between the Selected Patient and the Potential Duplicate, the user chooses “Dissolve the association between the Selected Patient and the Duplicate #”.

[0525] To terminate reconciling the two patient records, the user clicks Cancel.

[0526] To view the details of a patient, the user highlights the column containing the patient to view and clicks View Details. The Patient Details window appears.

[0527] To show the identifiers for each patient, the user clicks Show Identifiers. The list “jumps” to the fields containing the identifiers for the patients.

[0528] To view a graphical representation of the table, the user clicks Graphical. In response, a graphical representation window appears, as shown in FIG. 56. The user can click and drag a patient-bubble across this window. To view details of the patient record, the user can double-click on a patient-bubble and select View Details from the menu that appears. To reconcile a patient record, the user can double-click on a patient-bubble and select Reconcile from the menu that appears. To return to the Finding a Patient with Links table window, the user clicks Back. To print the Finding a Patient with Links table window, the user clicks Print.

[0529] Patients: Manage Patient Groups

[0530] The Manage Patient Groups menu option enables the user to create patient categories that are identified by a code and to sort patients into these various categories. Examples of patient groups are “High HDL Cholesterol Group”, “Diabetes Control Group”, and “E. Coli Testing”. Patient Groups with Report Groups are used to generate Results Summary Reports and Cumulative Reports. Information obtained from these reports can be used to schedule patient visits in advance, gather valuable statistical information and identify trends in a patient population.

[0531] When the user choose Manage Patient Groups from the Patients menu, the Patient Group Management window appears, as shown in FIG. 57. From the Manage Patient Groups menu option the user can:

[0532] List all patient groups

[0533] List all the patients in a patient group

[0534] Create New patient groups

[0535] Add a new patient to a patient group

[0536] View a patient group

[0537] View details of each patient in a patient group

[0538] Modify details in a patient group

[0539] Remove a patient group

[0540] Remove a patient from a patient group

[0541] Print a list of all the patient groups

[0542] Print details on a specific patient group

[0543] The user can follow the following procedures to view or modify an existing patient group from the Patient Groups Management window.

[0544] 1. On the Patient Groups Management, highlight the patient group to view or modify and click Details. The Patient Group Details window appears for the selected patient group, as shown in FIG. 58. The Description field is a description of the patient group. The Patient Group Code field is the patient group code. The Provider field is the provider for which the patient group was created. The default value for this field is the active HDN Business.

[0545] 2. View or modify the fields at the top of the screen.

[0546] 3. Add and/or remove patients on the Patients included in this Group list. To add a patient to the group, click Find. The Finding a Patient window appears. Find an existing patient or create a new patient to add to the patient group. The patient is added to the group. To get details of a patient previously added to the group, highlight the patient and click Details. The Patient Details window appears with the Chart Page 1 page active and the information last entered for the patient populating the fields.

[0547] Patients: Patient Group Listing

[0548] The Patient Group Listing menu option of the Patients menu enables the user to preview or print a list of all the patient groups for each provider that are created through the Manage Patient Groups function. The items on the list appear sorted in alphabetical order. A header page is a configurable option. The header pages shows: Date and time of the report, Name of the user running the report, Comment line, and Search criteria used to generate the report.

[0549] To generate the Patient Group Listing, the user selects Patient Group Listing from the Patients menu. The Patient Group Listing window appears, as shown in FIG. 59. The user then enters criteria for generating a patient group listing. FIG. 60 illustrates a Patient Group Listing Print Preview window for previewing a report.

[0550] User Module

[0551] In one embodiment, there are four basic functions to the User module of The system:

[0552] Change Active HDN Business

[0553] Change Password

[0554] Manage Preferred Lists

[0555] View Documents

[0556] These functions are accessed through the User menu, as shown in FIG. 61, or the User desktop menu. The User functions are described below. Before discussing these functions, a brief overview of security considerations is given.

[0557] Security Considerations in the system

[0558] The system provides the ability to secure information across a large and open network of computers and the people that use them. This network is referred to herein as a Health Data Network, or HDN. The security of this network, including access to it, is critical because the system provides access to confidential patient information, including laboratory test results and medical history.

[0559] User Accounts—Before the user can log on to the system, the user must have a user account including a logon name and a password. The user account provides the needed security for controlling access to the HDN and identifies the user while the user is using the system.

[0560] HDN Businesses—When the user log on to the system, the user connects to the system on behalf of a Health Data Network (HDN) Business. An HDN Business is any business, including a hospital, clinic, physician office, laboratory, payer, or employer, that participates in the creation and sponsorship of a specific HDN.

[0561] Through the user's user account, the user is linked with HDN Businesses. The user may be allowed to log on to the system on behalf of more than one HDN Business. For example, the user's primary HDN Business may be the office in which the user is currently working, but there may also be times when the user may need to access the system on behalf of a hospital where the user has patients in order to check on their status. In this case, the user may be linked to both HDN Businesses, the user's office and the hospital.

[0562] Parent-Child HDN Businesses—If the user's practice has more than one location or business unit, and all orders and results are shared throughout the practice, the user's practice may be configured as a single HDN Business. In this case, the practice's data may be stored in a central location and can be accessed by all users who have the appropriate permissions.

[0563] However, if the user's practice has more than one location or business unit, and the need exists to keep orders and results isolated within a location or business unit, the practice may be configured in a parent-child HDN Business relationship. This prevents lab orders and results and other data associated with one location or business unit from being accessed by users logged on to other locations or business units of the practice.

[0564] 1. A parent HDN Business is created for the entire practice.

[0565] 2. Child HDN Businesses are created for each business unit or location. Some business units or locations may actually share a single child, while others may be set up as individual child HDN Businesses.

[0566] 3. All child HDN Businesses are linked to the single parent HDN Business.

[0567] 4. The user's user account is associated with each child HDN Business where the user are permitted to access the information. The user's account may not be associated with all child HDN Businesses for the practice. Some advanced users may have their account associated with the parent HDN Business so they can carry out global administrative functions.

[0568] The data for the user's practice is then stored at two levels:

[0569] 1. At the parent-level, the following information is stored and available to all child HDN Businesses of that parent HDN Business:

[0570] Patient records and supporting information, excluding orders and results

[0571] Payers

[0572] Providers and caregivers

[0573] Codes, including diagnosis codes (ICD-9), test codes, analyte codes, report codes and profile codes

[0574] Report groups, patient groups and test groups

[0575] System configuration

[0576] When the user add any of these items to the system, they are available to all child HDN Businesses associated with the parent HDN Business.

[0577] 2. At the child-level, the following information is stored on behalf of and is only available to users logged on to that child HDN Business:

[0578] User preferences

[0579] Orders

[0580] Results originating from orders transmitted on behalf of the child HDN

[0581] Business

[0582] The orders, results and user preferences for each child HDN Business are isolated from the other child HDN Businesses. The only way a user can access this information is to log on to the child HDN Business. If the user are logged on to the parent HDN Business and have the appropriate permissions, the user can access all information for the practice, including the orders and results stored specifically for a child HDN Business.

[0583] Healtheon Field Service Representatives work with the user's practice to best determine the configuration of the user's system from the perspectives of data management and security.

[0584] Permissions, Roles, Operations and Objects

[0585] In addition to the ability to log on to the system on behalf of an HDN Business, users also must have permission to actually use the many functions of the system, and need access to the data stored across the HDN. As part of creating the user's permission profile, the user is assigned a role that the user performs when working with the system. This includes information regarding the types of data the user needs to be able to access and the functions the user needs to carry out on that data.

[0586] Types of data are referred to as objects and functions are referred to as operations. Patient records, lab requisitions, lab results, test codes, ICD-9 codes, lab profiles and physician profiles are examples of objects. An example of an operation is adding new objects. Viewing, modifying, printing, and deleting existing objects are also examples of operations. The process of searching for existing objects is also considered an operation.

[0587] A role defines what objects a user can access and what operations a user is allowed to carry out on each of those objects. For example, one role may allow users to add, view, modify, print and delete lab test requisitions, while another role may only allow users to view and print lab test requisitions.

[0588] When a permission profile is defined for the user, it is specific for an HDN Business. If the user belongs to more than one HDN Business, the user may have more than one permission profile. Each of these profiles may be different. For example, the user may have permission to add, view, modify, print, and delete patient records on behalf of one HDN Business, but the user may only have permission to view and print patient records on behalf of another HDN Business.

[0589] Effective dates and expiration dates may also be set for each permission profile, creating a limited period of time when that permission profile is in effect. This can be useful, for example, if a first user is going to be temporarily out of the office and the first user needs to be able to allow a second user to do the first user's work while the first user is gone. The permission profile for the second user can be set to begin the first day the first user is out of the office and to expire at the end of the day before the first user returns.

[0590] An administrator may work with users to ensure that the permission profiles and roles selected for each user are sufficient to meet the users' job requirements.

[0591] User: Change Active HDN Business

[0592] When the user logs on to the system, the user is connected to the HDN on behalf of an HDN Business. The user may select a default HDN Business at login time. For example, after entering a username and password, a popup window may appear with a list of HDN Businesses to choose from. Once the user log on to the system, a message at the bottom of the screen displays the name of the user's current HDN Business.

[0593] The Change Active HDN Business menu option of the User menu enables the user to select another HDN Business after the user has logged on to the system, provided that the user has permission to access more than one HDN Business. This permission may be set up by an administrator. When the user chooses the Change Active HDN Business menu option, the Change HDN Business dialog box appears, as shown in Figure 62. The list includes HDN Businesses with which the user is associated but that are not currently active. After switching to another HDN Business, the switch can be confirmed by checking the status bar, as shown in FIG. 63.

[0594] User: Change Password

[0595] The Change Password menu option of the User menu enables the user to change the user's account password. The Change Password dialog box may impose different criteria for determining whether a password is a valid password, depending on how an organization has configured this function.

[0596] User: Manage Preferred Lists

[0597] Preferred lists are a time saving feature that enable the user to carry out repetitive tasks more efficiently. The Manage Preferred Lists menu option of the User menu provides a means to carry out various recurrent tasks quickly without having to go through multiple screens and numerous keystrokes. In one embodiment, the system enables the user to set the user's own preferences for:

[0598] Caregivers

[0599] HDN Businesses

[0600] Payers

[0601] ICD Diagnosis Codes

[0602] ICD Procedure Codes

[0603] CPT Codes and

[0604] Test Codes

[0605] The system enables the user to maintain and modify these preference lists to suit the user's own requirements. Setting up preference lists helps the user streamline many tasks the user does within the application. The following is a sample of some common repetitious tasks that the user can be simplified by using preferred lists:

[0606] Creating Requisitions

[0607] Generating Lab Reports

[0608] Entering Insurance Information for a Patient

[0609] In the Preferred List Manager window, shown in FIG. 64, two separate lists appear side by side. On the left side of the screen, there is a list of Available items. On the right side of the screen, there is a list of Preferred items. New entries can be added to both lists.

[0610] From the Manage Preferred Lists menu option the user can:

[0611] Retrieve a preferred list.

[0612] Add items to a preferred list

[0613] Modify items on the user's preferred list

[0614] Remove single or multiple items from the user's preferred lists

[0615] Apply a Custom Filter to narrow down the user's search results

[0616] Get Details on any preferred list item

[0617] Print a preferred list

[0618] Shared Lists—The user can view the preferences of another user at the user's HDN Business or at another HDN Business and use items from their existing preferred lists to create the user's own list. There are two types of preferences: shared and individual. For example, in the case of caregivers, the user can have a My Caregivers preferred list and a Shared Caregivers preferred list.

[0619] Under the My Caregivers preferred list, a user may include those caregivers that only that user uses on a regular basis. Under the Shared Caregivers preferred list, the user may include those caregivers that are accessed by that user as well as other users associated with the active HDN Business. The user can have two types of preferred lists for other categories as well (HDN Businesses, Payers, ICD, CPT and Test Codes, etc).

[0620] Each HDN Business can set up its own list of preferences and make this list accessible to all users at that HDN Business. A user can have a different preferred list of items for every HDN Business the user has access to.

[0621] When the user displays a preferred list, the shared and individual lists may be combined and sorted in various ways, depending on what type of data the lists contain. For example, lists of caregivers, HDN Businesses, and payers maybe sorted in alphabetical order, whereas lists of ICD, CPT and test codes may be sorted numerically by code. Each item on a list may also have a descriptive comment next to it.

[0622] Users may own their preferred lists so that the entries a user makes to the user's preferred lists can be deleted only by that user. The HDN Business user preferences are accessible to all the users at that HDN Business. In one embodiment, they can be modified or deleted by any user at the HDN Business. Preferences may be linked to the user's account rather than to the user's workstation. Thus, the user can view the same preference lists regardless of the workstation used to access the system.

[0623] User: View Documents

[0624] An HDN business typically sends, receives, and stores many reports and other documents. Although these documents are often generated electronically by the various participants in the delivery of healthcare services for a patient, including health care providers, hospitals, labs and payers, the documents are traditionally printed and distributed by a number of different manual delivery methods, such as interoffice mail, facsimile, US Mail, or some other physical delivery method.

[0625] The View Documents menu option of the User menu provides instant, two-way, electronic communication between the various participants in the delivery of healthcare services for a patient. Documents, such as those described previously, can be linked to a user or list of users and then listed on their User Document List, shown in FIG. 65. From the user's User Document List, the user can:

[0626] View the document

[0627] Link the document to a patient record

[0628] Forward the document to another user or group of users

[0629] Documents that are not generated electronically or are from a source not participating in the Health Data Network (HDN), such as an employer, can be faxed into the user's system and then linked to a user or list of users. The faxed document is then treated like any other document generated electronically within the HDN.

[0630] The following table provides definitions for the columns on the User Document List window: Colunm Description Category The document category Date Created The date the document was created Document Source The source of the document Document Type The type of document From The user who forwarded the document to the user Linked To The person to whom the document is linked Status The read status of the document. A “U” indicates that the document is unread Urgent An exclamation point (“!”) indicates an urgent document

[0631]FIG. 66 illustrates a window for applying a custom filter to the User Document List.

[0632]FIG. 67 illustrates a window for viewing a user document.

[0633]FIG. 68 illustrates a window for editing the link for a user document.

[0634]FIG. 69 illustrates a window for forwarding a user document to one or more users.

[0635] Admin Module

[0636] Tasks carried out in the application comprise administrative as well as user tasks. Administrative tasks are found on the Admin menu, as shown in FIG. 70, which includes a Site Configuration option and the following five submenus:

[0637] Manage Businesses

[0638] Manage Security

[0639] Manage Health Care Codes

[0640] Manage Resources

[0641] Manage System Integration

[0642] It is noted that some or all of the functions accessible via the Admin menu may be restricted for use only by users with administrative privileges. Thus, in the following descriptions of the Admin menu options and submenus, the term “the user” may refer to administrative users.

[0643] Admin: Site Configuration

[0644] Before using the Admin menu options to configure the user's site, it is important to have an understanding of Health Data Network (HDN) Businesses, and how they relate to other system components. The user must also understand the concept of parent-child relationships in order to successfully maintain the user's site.

[0645] In the preferred embodiment, the system can interface to multiple labs simultaneously and seamlessly. The Site Configuration option in the Admin menu enables the user, e.g., an administrator, to support and manage this feature and provides the user the functionality needed to define relationships between the user's site and several laboratories.

[0646] When selected, the Site Configuration window appears with the General page active, as shown in FIG. 71. This page is used to specify HDN Business level interface settings that affect how the system works.

[0647] The Lab page, shown in FIG. 72, is used to define and maintain information on provider-lab associations. Before an order can be sent from a Provider HDN Business, that business must have at least one lab association and one client ID for that association. From this page, the user can carry out the following functions:

[0648] Create, configure and maintain associations between a provider and multiple labs

[0649] View and/or modify detailed lab information

[0650] Create Client IDs for each provider-lab association

[0651] View and/or modify information on existing Client IDs

[0652] Print configuration data, lab association information and Client IDs for a provider

[0653] Site Configuration—General Page

[0654] As described above, a user's practice may be configured as a parent-child HDN Business relationship. To modify the configuration data of the table shown in FIG. 71, the user may log in to the parent HDN Business. A message appears at the top of the page in FIG. 71 indicating the name of the HDN Business the user is currently viewing.

[0655] When the user views a child HDN Business, the configuration data that appears on the screen may be that of the parent HDN Business. In one embodiment, any configuration data defined at the parent level cannot be modified at the child level. When viewing information for a child business, any parent-specific data may appear grayed out on the configuration table so that the data cannot be modified. As described above, individual HDN Businesses may have their own policies regarding what permissions a user can have. Thus, a Business may define a policy such that only administrators are allowed to define or modify configuration information.

[0656] The following table explains the fields on the General page of the Site Configuration Details window: Field Name Definition Account Path for PMS The account path for a Practice Management Interface System (PMS) interface. Baud rate for PMS The baud rate for the PMS interface. Interface Client Type The client type. Databits for PMS The number of databits for the PMS interface. Interface Default Bill Type The default bill type. Includes drop-down list values of: Client, Patient or Third Party. The value selected appears as the default Bill Type when creating a requisition. Interface for the PMS The interface for the PMS system. System Months before results The number of months before results are ready to be archived. Parity for PMS The parity for the PMS interface. Interface Patient Label Barcode Indicates the method used for encoding Format information in the patient label bar code. PMS Check Required This box tells the system to search for patient records in the Practice Management System Port for PMS Interface The port for the PMS interface. Print Patient Label Indicates whether patient labels are printed. If this box is selected, a label is printed when a requisi- tion is created, as long as a label printer is attached to the workstation where the requisition is created. Labels are placed on specimens for identification purposes. Refresh Results The frequency at which the results statistics in the Statistics main screen status bar are updated. (Not Viewed Frequency (hours) Results, Abnormal Results) Single User Site Indicates if the site is a single user site. Stopbits for PMS The number of stopbits for the PMS interface. Interface

[0657] Site Configuration—Lab Page (FIG. 72)

[0658] Providers can preferably send orders through either parent or child labs, as long as they are orderable labs. Orderable labs are those that a client can directly send orders to. For every set of labs associated with a provider, one of the labs may be setup as the default lab. Each Provider HDN Business may have a set of Labs associated with the Provider and a set of Client IDs linked to the Provider. The Lab page of the Site Configuration window, shown in FIG. 72, includes functions for managing this information.

[0659] The Laboratory Associations portion of the Site Configuration Details window allows the user to define and maintain associations between the user's site and various labs. These lab associations must be defined before a Provider HDN Business can send orders to one or more labs. The associations between a Provider HDN Business and a set of orderable labs may be defined at the parent level, and child HDN Businesses may inherit the lab associations of their parent HDN Businesses.

[0660] The management and creation of lab detail information may be performed through the Labs subsystem of the Manage Businesses submenu option, as described below. The user can also view and modify lab detail information on labs accessed through the Site Configuration Details window. In the Laboratory Associations section of the Lab page the user carry out the following functions:

[0661] Create and configure associations between a site and one or more labs

[0662] View and/or modify detailed information on existing labs

[0663] Print lab association information

[0664] To configure a provider-lab association, the user highlights the provider-lab association to configure and clicks Configure. In response, the Lab Association Configuration window appears, as shown in FIG. 73. The user may then modify the fields on the page as needed. The following table explains the fields found on the Lab Association Configuration window: Field Name Definition Allow manual If this box is selected, manual requisition numbers requisition numbers can be entered when creating a requisition. Otherwise, each new requisition uses a number generated by the system. Eligibility results This field applies primarily to Future requisi- rechecked after tions. If eligibility has been verified for a delay of (hours) requisition, patient or insurance within the specified number of hours, it will not be re-checked. Otherwise, it will be verified again. Exclude Bill Type A drop-down list with possible values of Client, Patient or Third Party. If a value is selected then that Bill Type cannot be used when creating a requisition. FDA check required When this box is selected, if Bill Type is Third Party and the patient has a limited coverage policy, such as Medicare, and a non FDA- compliant test code is used in a requisition, the ABN Dialog box appears. An Advanced Beneficiary Notice (ABN) is a printed statement that includes a list of tests not covered by the payer. HDN Business The Provider HDN Business being linked to a lab. Also, the currently active HDN Business. This is a read only field and cannot be modified. Lab The Lab associated with the Provider. This is a read only field and cannot be modified. LCP check required When this box is selected, if Bill Type is Third Party and the patient has a limited coverage policy, such as Medicare, and a non LCP- compliant test code is used in a requisition, the ABN Dialog box appears. An Advanced Beneficiary Notice (ABN) is a printed state- ment that includes a list of tests not covered by the payer. Maximum requisition This field is used to designate the maximum number requisition number that can be entered, regardless of whether manual or automatic requisition numbers are used. Minimum requisition This field is used to designate the minimum number requisition number that can be entered, regardless of whether manual or automatic requisition numbers are used. Selec Test Only Accepts one of two possible values, Yes or No. Specificity check When this box is selected, if a user enters required an ICD-9 code in a requisition that has more specific designations or codes, the user is required to select a more specific ICD-9 code instead of the non-specific one. Transfer ID A unique identifier assigned to each site. This field is used during the process of uploading and downloading results. Multiple client IDs may map to the same transfer ID.

[0665] It is noted that for every set of labs associated with a provider, one lab may be selected as the default lab. The default laboratory may be used for requisitions that have patient or client billing. However, when creating a requisition, a user can send the order to any lab associated with the provider HDN Business, even if another lab has been defined as the default lab.

[0666] The Client IDs portion of the Site Configuration Details window allows the user to create and maintain client ID information for the user's site. Client IDs are used for billing and for distributing lab results. Providers must have Client IDs in order for them to be able to send orders to a lab. In addition to the default client ID for the user's site, the user can also have numerous client IDs associated to different caregivers and to the user's site. For businesses that have a parent-child relationship, the workstation client IDs may be linked to child HDN Businesses so that the results ordered can be returned to the originating workstations. To support the proper distribution of results based on client ID, client IDs can be stored at the parent or at the child HDN Business level. For every set of client IDs associated with a provider, one ID may be selected as the default client ID.

[0667] In the Client IDs section of the Lab page the user can perform the following functions:

[0668] Create Client IDs for each provider-lab association

[0669] View and/or modify information on existing Client IDs

[0670] Print information on Client IDs

[0671]FIG. 74 illustrates a window for creating or editing a Provider-Lab Client ID. The following table explains the fields found on the Provider-Lab Client ID Details window: Field Name Definition Caregiver This is the name of the physician to whom the provider client ID is assigned. If no physician is selected, the client ID is defined for the provider. Client ID The lab assigned identifier for the provider. Default Client ID This check box indicates if the client ID is the default ID for the provider. Description A description of the associated provider caregiver. Lab The lab associated with the provider. This field cannot be modified. Provider The name of the provider to whom the client ID is assigned. This field cannot be modified.

[0672] Admin: Manage Businesses

[0673] In a health care delivery system, businesses rarely finction as standalone units. Because of the layered business structures that exist in today's health care industry, flexibility is needed to define and manage business units. With the Manage Businesses submenu, the user has the flexibility to manage various types of businesses. These business types may include the following: Business Type Definition Employers A company that the patient, insured party, or guarantor works for. Labs An organization that provides clinical testing and observation. Payers A party responsible for paying the lab bill, usually a commercial health insurer or government agency that underwrites or administers programs that pay for health services. Providers An institution or individual that gives medical care.

[0674] Business subsystems for managing these business types may be accessed through the Manage Businesses option of the Admin menu, as shown in FIG. 75.

[0675] Admin: Manage Businesses: Employers

[0676] Although the employers of patients, insured parties, and guarantors are not directly involved in the delivery of healthcare, they are part of the business structure. Using the Employer menu option of the Manage Businesses submenu, the user can carry out the following functions:

[0677] Create new employer records

[0678] View and/or modify existing employer records

[0679] Print employer records details

[0680] Delete employer records

[0681] Print lists of employers

[0682] Once created, employer records can then be linked to patient, insured party and guarantor records.

[0683] Admin: Manage Businesses: Labs

[0684] A lab may be an organization that provides clinical testing and/or observation services. Using the Labs menu option of the Manage Businesses submenu, the user maintains information on the labs the user does business with. This information may be used by functions accessed via the Orders menu, which include utilities used to prepare and submit requisitions. In the Labs subsystem, the user can carry out the following functions:

[0685] Create new lab records

[0686] View and/or modify existing lab records

[0687] Print lab records details

[0688] Delete lab records

[0689] Print lists of labs

[0690] In addition to basic demographic information, each lab record may include information shown in the following table: Information Type Definition Child Labs These are the children of a parent lab. Not all labs have child labs. Configuration These are the configuration settings for the lab. Payers These are the payers associated with the lab that have electronic eligibility.

[0691]FIG. 76 illustrates the Lab Details window, for creating a new lab or modifying details of an existing lab. The following table explains the fields found on the Lab Details window: Field Name Definition Address The lab address. Alt. Name An alternative name that identifies the lab. City The city for the lab mailing address. Director's Name The name of the lab director. Federal Tax ID The lab Federal Tax Identification number. Lab Code A user-defined identifying code for the lab. Name The complete name of the lab. Orderable If this box is selected the lab is an orderable lab. An orderable lab is one that a client can directly send orders to regardless of how a Provider HDN Business is setup. Parent lab If the lab is a child, this field contains the name of the parent lab. Phone The phone number of the primary contact at the lab. Sec. Dir. Name: An alternate contact for the lab director. State The 2-character abbreviation for the name of the State in the lab mailing address. Transmission mode The transmission mode used by the lab. In general, sponsoring labs use electronic transmission, while generic labs use manual or paper based transmission. Zip The zip code for the lab address.

[0692] To access the Configuration page, the user clicks Configuration on the Lab Details window. In response, the Configuration Details window appears, as shown in FIG. 77. The Configuration Details window enables the user to define lab level settings for a specific lab. These settings may affect how some of the data is stored in the system, as well as the process of creating requisitions and the use of lab records. They also affect the relationship between labs and payers. From this page the user can define the level of data ownership for a lab: parent only, child only, or a combination of both. This page enables the user to specify what data is stored at the parent level and what data is stored at the child level.

[0693] The following table explains the fields found on the Configuration page of the Lab Details window. Note that a Parent? check box appears next to every configuration field. This box indicates the level of ownership, parent or child, for each field. If the Parent? box is checked, this means the setting is defined at the parent level and the children of that lab will inherit that value. The field appears grayed out or disabled when viewed from a child lab. If the Parent? box is unchecked, this means the setting is deferred to the children of that lab. The field is enabled when viewed from a child lab. Field Name Definition Default Billing The default Host System Identifier for a Payer. Mnemonic Max diagnoses The maximum number of diagnosis (ICD-9) per test codes allowed per test. Max tests per The maximum number of test codes allowed in a requisition requisition. Max copy to per The maximum number of Caregivers to receive requisition copies of a requisition. This field affects the list of caregivers in the Additional Info page of a requisition. Copy to electronic This check box affects the physician results list in only? the Additional Info page of a requisition. If this box is checked, the search only returns caregivers that have Client IDs. Otherwise, the search returns all caregivers that meet the user's search criteria. Print Specimen This check box determines whether a specimen Barcode bar code is printed when a requisition is created. Specimen Barcode Defines the method used for encoding information Format in a bar code. A value may be selected from the drop-down list. Requisition Report Defines the requisition report format. A value Format may be selected from the drop-down list. Single Result Report The format of a typical result report. A value may Format be selected from the drop-down list. Logo Filename/Path This is the file name and location of the logo image that appears on a requisition. Transfer ID Format Specifies the transfer ID format. (X means any alphanumeric character is allowed, N stands for numeric, A stands for alpha, and anything inside quotes is a literal string or code). Client ID Format Specifies the Client ID format. (X means any alphanumeric character is allowed, N stands for numeric, A stands for alpha, and any text inside quotes is a literal string or code). Billing Mnemonic Specifies the Billing Mnemonic format. (X means format any alphanumeric character is allowed, N stands for numeric, A stands for alpha, and any text inside quotes is a literal string or code). Eligibility Checking The eligibility checking mode for the lab. This field may have a value of Always OFF, Always ON, or ON by Payer. (See below.) Transaction Routing The lab Transaction Routing Method. This field Method affects electronic transmissions. For generic labs, the field can be left blank.

[0694] Eligibility Checking—Some labs prefer to have eligibility checking or enabled for all payers, some labs want this feature disabled all the time, and other labs want to be able to select which payers to perform electronic eligibility checking on. The system may support these different scenarios by providing various settings for checking eligibility. The user may specify these settings through the Eligibility Checking field which appears on the Configuration page of each lab.

[0695] In one embodiment, the user can set the Eligibility Checking field to be one of the following: OFF Always; ON Always; or ON by Payer. If the user selects the ON by Payer option, the user can select payers from an existing set of payers that have been globally enabled for electronic eligibility within the system. Eligibility payer lists may be defined at the same lab level (parent or child) that the Eligibility Checking configuration option is defined.

[0696] To access the Child Labs page, the user clicks Child Labs on the Lab Details window. In response, the Child Labs window appears, as shown in FIG. 78. The Child Labs page lists the children of a parent lab. This relationship is established when a Parent lab is selected for a child lab on the Lab page of the Lab Details window. When the user views a parent lab that has children labs, the Child Labs page is active and it includes a list of all the children labs. When the user views a parent lab that has no children labs, the Child Labs page is active, but no labs are listed.

[0697] From the Child Labs page, the user can carry out the following tasks:

[0698] View details of existing child labs

[0699] Modify detail information of existing child labs

[0700] Modify the parent-child relationship between two labs

[0701] To access the Payers page, the user clicks Payers on the Lab Details window. In response, the Payers window appears, as shown in FIG. 79. Payers can have contractual agreements with some labs, wherein if the lab work for a patient is sent to a contracted lab, there is a financial benefit to be gained by the payer. The lab-payer associations are typically defined at the parent lab level, but the system does not restrict it to this level. The association between labs and payers is managed through the Payers page of the Lab Details window. The Payers page includes a list of payers associated with a lab that may be checked for eligibility if electronic eligibility is enabled.

[0702] From this page, the user carry out the following tasks:

[0703] Associate existing payers with labs

[0704] View details of existing payers

[0705] Remove existing associations between payers and labs

[0706] Admin: Manage Businesses: Payers

[0707] A payer typically refers to an insurance company, but it can mean any organization, such as an employer or government agency, that pays for medical services provided to a patient. A payer is different than a guarantor. The guarantor is the person ultimately responsible for payment of the medical bill. For example, if the insurance company does not cover medical charges, the guarantor, which is usually the patient or the patient's guardian, is responsible for payment.

[0708] Using the Payers menu option of the Manage Businesses submenu, the user can carry out the following functions:

[0709] Create new payer records

[0710] View and/or modify existing payer records

[0711] Print payer records details

[0712] Delete payer records

[0713] Print lists of payers

[0714] In addition to basic demographic information, each payer record may include the following information: Information Type Definition Providers Providers and caregivers for whom the payer cover medical expenses. Service Services on the network that the payer participates in. Billing Lab-defined billing IDs for the payer. Insurance Code A user defined value used to identify a payer. Labs The labs for whom the payer will cover medical expenses.

[0715] Because the number of payers stored on the user's system may be very large, the user can create a list of preferred payers as described above. The Preferred List of Payers may include those payers that the user frequently uses, which makes locating a payer much easier and faster. This Preferred List of Payers can be defined through the Manage Preferred Lists option of the User subsystem or by selecting Add to List(s), either Shared List or My List, when carrying out a find function for a payer.

[0716]FIG. 80 illustrates the General page of the Payer Details window. The General page includes fields specifying general information regarding a payer.

[0717]FIG. 81 illustrates the Providers page of the Payer Details window. A provider is any organization that supplies health care-related services, such as a hospital, clinic, lab, and diagnostic center. On the Providers page in the Payer subsystem, the user can view the providers and caregivers for whom the Payer will cover patient expenses. The user may pick either a provider or caregiver to show their identifiers associated with the payer. These providers may be used for assigning IDs used in billing. (i.e., IMO provider ID). Management of payer-providers is carried out through the Providers page of the Payer Details window.

[0718]FIG. 82 illustrates the Service page of the Payer Details window. Claims and eligibility verification are examples of payer-related services in the system. The system allows payers to interface with these services. Management of payer-services is carried out through the Service page of the Payer Details window. For each Payer-service definition, the user can link a payer with a service and indicate the interface method used for the service.

[0719]FIG. 83 illustrates the Billing page of the Payer Details window. A lab identifies a payer by a billing ID. If the payer is to be billed for a requisition, the payer's billing ID is sent to the lab with the requisition. The Billing page of the Payers subsystem lists the lab-defined billing IDs for the payer that the user selects. Management of payer-billing identifiers is carried out through the Billing page of the Payer Details window.

[0720]FIG. 84 illustrates the Insurance Code page of the Payer Details window. This page shows the insurance codes for a payer. An insurance code is a user-defined identifier used to designate a payer. Each site can have more than one insurance code to designate the same payer. Management of payer-insurance codes is carried out through the Insurance Code page of the Payer Details window.

[0721]FIG. 85 illustrates the Labs page of the Payer Details window. The Labs page shows all the labs associated with the active payer. These labs are considered payer-approved labs. Payers can have contractual agreements with some labs wherein if the lab work for a patient is sent to a contracted lab, there is a financial benefit to be gained by the payer. For each lab-payer set, each provider HDN Business can specify which lab in the set is their preferred one to use.

[0722] When creating a requisition, the user may choose what lab to send the order to. For patient and client billing, the lab may default to the default lab for the ordering provider HDN Business, although a user can choose from any lab associated with the provider. For third party billing, the payer is chosen first then the lab defaults to the payer preferred lab if one exists, then to the HDN Business level default lab if that lab is in the payer-lab list, or to nothing if neither of these conditions apply. Again, the user can choose any of the labs setup for the Provider HDN Business and override any default labs.

[0723] The association between labs and payers is managed through the Labs page of the Payer Details window. From this page, the user can carry out the following tasks:

[0724] Associate existing labs with a payer

[0725] Designate a lab-payer combination as preferred

[0726] Remove existing associations between labs and payers

[0727] Admin: Manage Businesses: Providers

[0728] A provider is any organization that supplies health care-related services, such as a hospital, clinic, lab, diagnostic center, etc. Using the Providers menu option of the Manage Businesses submenu, the user can maintain information on the Providers in the user's network. In the Provider subsystem, the user can perform the following functions:

[0729] Create new provider records

[0730] View and/or modify existing provider records

[0731] Print provider records details

[0732] Delete provider records

[0733] Print lists of providers

[0734] In addition to basic demographic information, each provider record may include the following information: Information Type Definition Caregiver Caregivers associated with the provider Client IDs Physicians' client IDs for particular labs Specialties Specialties of the provider

[0735]FIG. 86 illustrates the General page of the Provider Details window. The General page includes fields specifying general information regarding a provider.

[0736]FIG. 87 illustrates the Caregiver page of the Provider Details window. A caregiver is a person who provides health care services to patients. Physicians, nurses, technicians, and physician's assistants are all examples of caregivers. In the business of healthcare, caregivers are typically associated with providers. The management of this association is carried out through the Caregiver page of the Provider Details window. From this page, the user can carry out the following tasks:

[0737] Associate existing caregivers with providers

[0738] View details of existing caregivers

[0739] Remove existing associations between caregivers and providers.

[0740]FIG. 88 illustrates the Specialties page of the Provider Details window. A specialty defines a specific area of medicine, such as cardiology, pediatrics, or oncology, that a provider supplies. On the Specialties page of the Providers subsystem, the user can view specialties associated with the selected Provider. Each specialty record includes a description, and the specialties are linked to caregivers. Management of provider specialties is carried out through the Specialties page of the Provider Details window.

[0741]FIG. 89 illustrates the Client IDs page of the Provider Details window. The caregivers listed in the Client IDs page are a subset of those listed in the Caregiver page. The list of caregivers on the Client IDs page is based on the caregivers linked to the selected provider who have been assigned Client IDs by a particular lab. Generally these caregivers are physicians, but any caregiver type can be assigned a Client ID.

[0742] A caregiver must have a client ID when he or she submits a requisition to a laboratory. If the caregiver does not have a client ID, he or she uses the default client ID, which is assigned to the caregiver's HDN Business. The default client ID is typically used only when the ordering caregiver does not have a client ID.

[0743] Management of provider client identifiers is carried out through the Client IDs page of the Provider Details window. The Client ID page lists physicians, their client IDs, and the labs where they have IDs assigned.

[0744] Admin: Manage Security

[0745] Security administration involves setting up and maintaining security aspects of the system. Using the Manage Security submenu of the Admin menu, the user, i.e., an administrator, can control user access to confidential patient information stored on the network. For example, the security features may prevent a data record from being viewed or modified by unauthorized users.

[0746] Security functions are accessed through the Manage Security submenu of the Admin menu, as shown in FIG. 90. The Manage Security menu option enables the user to manage key aspects of the system, such as shown in the following table: Key Aspect Description User Accounts Information about the people associated with an HDN Business who access the system. HDN Businesses Businesses connected to the Health Data Network. Realms Collection of security roles and permission profiles. Permission Profiles General grants of access given by an owner to a user. Security Roles Groups of operations that are typically related to a specific function or position.

[0747] After the user make changes to the security system, the user may update the users and realms through a Make Security Changes Effective menu option.

[0748] Security Checks—One important feature of the system is the secure exchange of information across a possibly very large and open network. To accomplish this, the system may check the following aspects of a user account before allowing the user to carry out a function: Security checks the . . . Which is a . . . Operation Task that a user carries out on the data stored on the HDN. Operations may be global to the entire HDN. Security Role Collection of typically related operations. Permission Profile Set of parameters for selected roles as they apply to users of an HDN Business. Realm Collection of roles and permission profiles.

[0749] Roles and Permissions—In the preferred embodiment, the security system is based on roles and permissions. These two concepts, combined with ownership, determine a user's authorization level, or the operations the user can carry out. A role is a group of operations that is typically related to a specific function or position. For example, various roles may be defined for physicians, nurses, office assistants, etc., or for any other function or position that a business desires. Roles limit transaction access to certain groups of users. For example, roles can be used to deny access to transactions related to clinical results except for people whose job requires that they have access. Only people with an approved need to know should be assigned roles that have search and read capabilities on patient information. The system users are classified and their permissions are assigned based on pre-defined security roles.

[0750] A permission profile is created from a role. The permission profile specifies the role's clearance level, effective date, expiration date, owner, and what realm it belongs to. A realm refers to a collection of roles and permission profiles. Usually the realm owns the permission profile, but it can also be owned by a user.

[0751] Admin: Manage Security: User Accounts

[0752] Users are people associated with one or more HDN (Health Data Network) Businesses who access the system, such as caregivers, physicians, staff members, and administrators. The User Accounts menu option of the Manage Security submenu may be used to manage information regarding the HDN Businesses a user is linked to and the permissions assigned to the user for a specific HDN Business.

[0753] Prior to adding users or modifying user information, an administrator may initialize the security system by creating a realm, business entity, roles, permissions, etc. Users may then be added and assigned to HDN Businesses with specific permissions. The User Accounts menu option enables access to the following information: Select this page . . . To see . . . General User attributes and information used to verify the user's identity HDN Business Status, active or inactive, of the selected user for the HDN Businesses listed Permissions Permission profiles for roles assigned to the user Site ID Healtheon Practice site IDs assigned to the user

[0754]FIG. 91 illustrates the General page of the User Account Details window. The General page includes fields specifying general information regarding a user account.

[0755]FIG. 92 illustrates the HDN Business page of the User Account Details window. HDN Businesses are associated with a user by clicking Add and then finding an HDN Business. The HDN Businesses page also shows the status (active or inactive) of the selected user for the HDN Businesses listed. To activate an inactive account, the user highlights the account and clicks Activate. To deactivate an active account, highlight the account and click Deactivate.

[0756]FIG. 93 illustrates the Permissions page of the User Account Details window. A permission is a general grant of access given by an owner to another user. A permission comprises an owner identifier, a user identifier, and a role identifier. Each permission may be mapped to a clearance level.

[0757] Permission profiles are assigned to users for a specific HDN Business. Users can have the same or different permission profiles with different HDN Businesses. The Permissions page shows the permission profiles for roles assigned to the selected user.

[0758]FIG. 94 illustrates the Site ID page of the User Account Details window. A Healtheon Practice site can be any health care entity, such as a caregiver, hospital department, or hospital. The site definition depends on the user's contractual agreement with Healtheon for using the Healtheon Practice system. The Site ID page contains a list of site IDs that the user can assign to the selected user. The user then has access to information at the specified Healtheon Practice site. The user set up the site IDs using the Site ID subsystem of the Manage System Integration option.

[0759] Admin: Manage Security: HDN Businesses

[0760] A Health Data Network (HDN) Business is any business connected to the Health Data Network. An HDN Business may or may not share data with other HDN Businesses. Using the HDN Businesses menu option of the Manage Security submenu, the information regarding the HDN Businesses in the Health Data Network may be managed. The HDN Business Details window provides access to the following information: Select this page . . . To see . . . General Specifics where the business fits in the network Contact Entity representatives Billing Reference and tax identification Users Attributes and identity verification Configuration Network participation

[0761] When a new HDN Business is created, it may be linked it to a Global Location. This is referred to as assigning a data slice to an HDN Business. There is a field on the HDN Business General page called Data Server. By selecting one of the data servers on the list the user link the HDN Business to a Global Location.

[0762] The following table explains the fields on the General page of the HDN Business Details window, shown in FIG. 95: Field Name Definition Data Server The data server where the data for the HDN Business is stored. HDN Business Link The business that is linked to this HDN Business. The type of business is determined by the value in the HDN Business Type field. On windows and printouts that include an address, such as a Requisition, the address from the linked business is used. HDN Business Name The name of the HDN Business. HDN Business Type The type of HDN Business. The value in this field determines which business can be selected in the HDN Business Link field. Parent HDN Business The parent HDN Business for the HDN Business. Realm The realm the HDN Business belongs to.

[0763] Admin: Manage Security: Realms

[0764] A realm is a collection of roles and permission profiles. A user's access to the system is determined by roles and permissions. The purpose of a realm is to specify the roles and permission profiles associated with an HDN Business. Each realm may include one or more HDN Businesses that use the same set of roles and permission profiles. Although a realm can include several HDN Businesses, an HDN Business can be linked to only one realm. Multiple realms may exist, one of which may be the hub realm.

[0765] Through the Realms menu option of the Manage Security submenu, the user can maintain the list of HDN Businesses in a realm. In addition, the user can define the roles and permissions for the realm. The Realm menu option enables access to the following information: Select this page . . . To see . . . General Realm name and description HDN Businesses HDN Businesses in the realm Permission Profiles Permission profiles associated with the realm Roles Roles associated with the realm Users Online Users currently online who have roles associated with a realm

[0766]FIG. 96 illustrates the General page of the Realm Details window. The General page includes fields for entering a name and description for a realm.

[0767]FIG. 97 illustrates the HDN Businesses page of the Realm Details window. The HDN Businesses page lists the HDN Businesses linked to the selected realm. If the HDN Business is a sub-business of another, the parent business entity is also listed. From this window, the user can carry out the following tasks:

[0768] Create New HDN Businesses that are automatically associated with the active realm

[0769] Get Details of an existing HDN Business the is associated with the active realm

[0770]FIG. 98 illustrates the Permission Profiles page of the Realm Details window. The Permission Profiles lists the permission profiles associated with a realm. From this window, the user can carry out the following tasks:

[0771] Create New permission profiles that are automatically associated with the active realm

[0772] Get Details of an existing permission profile the is associated with the active realm

[0773]FIG. 99 illustrates the Roles page of the Realm Details window. The Roles page lists the roles associated with a realm. From this window, the user can carry out the following tasks:

[0774] Create New security roles that are automatically associated with the active realm

[0775] Get Details of an existing security roles the is associated with the active realm

[0776] The Users Online page of the Realms Details window lists the users currently online who have roles associated with the specified realm.

[0777] Admin: Manage Security: Permission Profiles

[0778] A permission is a general grant of access given by an owner to a user. Usually the realm owns the permission profile, but a user can also be an owner. In one embodiment, a permission comprises a role, an owner, a clearance level, an effective date, and an expiration date. Thus, when a permission profile is assigned to a user, information may be specified, such as the operation the user can perform, the level of clearance entailed, and a beginning and ending date between which the operations can be performed.

[0779] Through the Permission Profiles menu option of the Manage Security submenu, the user, e.g., an administrator, can create permission profiles. The user can then assign the permission profiles to selected users. FIG. 100 illustrates the Permission Profile Details window, which can be used to create or edit permission profiles. The following table describes the fields found on the Permission Profile Details window: Field Name Description Assigned Users The users that this permission profile has been assigned to. Effective Date The date the permission profile becomes effective. Expiration Date The date the permission profile expires. Maximum The maximum clearance that can be assigned to users Clearance for this permission profile. Owner Type The type of owner for the permission profile. Owner Name The owner of the permission profile. Realm Name The realm for which the permission profile is created. Role Name The role for which the permission profile is defined.

[0780] There are preferably no limitations on the number of permission profiles that can be assigned to users. In one embodiment, permission profiles are limited to one role each, and more than one permission profile may be assigned to a user who has several roles. Also, the same permission profile may be assigned to different users who perform the same role. For example, three different hospital registration clerks could share the same role that allows them to view and modify patient information.

[0781] The following procedure may be used to assign a permission to a user:

[0782] 1. On the Permission Profile Details window, the user clicks Assign. In response, the first window of the Assign Permission wizard appears.

[0783] 2. The user then selects a Clearance level from the drop-down list for the field and clicks Next. The second window of the Assign Permission wizard appears.

[0784] 3. The user enters the Effective Date and Expiration Date for the permission assignment and clicks Next. The third window of the Assign Permission wizard appears.

[0785] 4. From the list of users, the user selects one or more users to assign the permission profile to.

[0786] 5. The user clicks Finish. The system validates the assignment. If the assignment was successful, the Permission Granted dialog box appears. If the assignment was not successful, the Permission NOT Granted dialog box appears.

[0787] Admin: Manage Security: Security Roles

[0788] As descried above, a role comprises a group of operations that is typically related to a specific function or position. Roles limit transaction access to certain groups of users. For example, roles can be used to deny access to transactions related to clinical results except for people whose job requires that they have access to this information. Only people with an approved need to know should be assigned roles that have search and read capabilities on patient information.

[0789] When the user creates a role in the Security Roles subsystem, the user names the role and specifies its realm. The user then selects from a list of available user accounts that are linked to one or more operations. The user can add and remove the user accounts that are associated with the role. The user maintains existing security roles similarly.

[0790] Defined roles may be available for permission assignment by any and all realms in the network. Roles defined locally by a realm may be available for permission assignment on that realm only.

[0791]FIG. 101 illustrates the Security Role Management window. From this window the user can:

[0792] filter the Security Role Management list

[0793] print the Security Role Management list

[0794] create a new security role

[0795] display details of an existing security role

[0796] create a permission profile for the highlighted security role

[0797] update the security roles

[0798]FIG. 102 illustrates the Security Role Details window for specifying or viewing details of a particular role. A security role comprises objects and the operations that can be carried out on those objects. The Security Role Details window has two panels, each with two lists. The top list in the left-hand panel displays all available objects. When the user clicks on an object, the list of operations that can be carried out on those objects appears in the list at the bottom of the panel. The top list in the right-hand panel displays all objects which have been assigned to the security role. When the user clicks on an object, the list of operations which can be carried out on that object that have been assigned to the security role appears on the list at the bottom of the panel.

[0799] To assign object-operations to a security role, the user clicks on an object in the Available panel and then selects the desired operations that users with this role should be able to carry out on that object. Clicking Add assigns the object-operations to the security role.

[0800] Admin: Manage Security: Make Security Changes Effective

[0801] Using the Make Security Changes Effective menu option of the Manage Security submenu, the user updates users and realms with changes that have been made to the security system, such as creating a new user or changing a user password. If this function is not performed, then the next time a user logs on to the system, the changes may occur anyway.

[0802] Admin: Manage Health Care Codes

[0803] Various sets of health care codes may be used throughout the system, as shown in the following list.

[0804] CPT-4 codes

[0805] ICD-9 codes

[0806] Specialties

[0807] Analyte codes

[0808] Profile codes

[0809] Report codes

[0810] Test codes

[0811] Code sets are accessed through the Manage Health Care Codes menu option of the Admin menu.

[0812] Analyte Codes—An analyte is the smallest unit or component for which a laboratory test is performed. A laboratory test may include multiple analytes. For example, a CBC (complete blood count) is a single test that includes multiple analytes. Analyte codes may be specific to a lab, and may be pre-loaded into the system. As updates become available, these may also be loaded into the system automatically, with no action required on the part of the user. Using the Analyte Codes function, the user can find and print codes. Analyte codes are used for viewing and reporting on results.

[0813] CPT-4 Codes—Current Procedural Terminology version 4 (CPT-4) codes can be used by physicians to report the services that they provide to their patients. These codes are used for evaluation and management. Because CPT-4 codes have been universally adopted in the healthcare industry, they are not specific to any one lab. These codes may be pre-loaded into the system. As updates become available, these may also be loaded into the system automatically, with no action required on the part of the user. Using the CPT-4 Codes function, the user can find codes and print lists of codes.

[0814] Because the number of CPT-4 codes stored on the system may be very large, the user can create a list of preferred codes, i.e., those codes that the user frequently uses. This makes locating a CPT-4 code much easier and faster. When the user selects Preferred from the CPT-4 Code field control menu, the Preferred List of CPT-4 Codes appears with the user's list and the shared list combined. This allows the user to see the list of preferred CPT-4 codes for the entire HDN Business, as well as those that the user have added for the user's own use. Even if the user is a new user, the user still has a Preferred List of CPT-4 Codes that includes codes from the shared list.

[0815] ICD-9 Codes—International Classification of Diseases version 9 codes (ICD-9coding) are used in clinical settings for reporting diagnoses and diseases to U.S. Public Health Service and Health Care Financing Administration programs. Because ICD-9 codes have been universally adopted in the healthcare industry, they are not specific to any one lab. These codes may be pre-loaded into the user's system. As updates become available, these may also be loaded into the system automatically, with no action required on the part of the user. ICD-9 diagnosis codes are used by functions accessed via the Orders subsystem, which includes utilities for preparing and submitting requisitions.

[0816] Using the ICD-9 Codes function, the user can find codes and print lists of codes. To simplify locating codes, the system differentiates between diagnosis and procedure codes. The list of ICD-9 codes on which to search is determined by the requirements of the field or list from which the search was initiated. Because the number of ICD-9 codes stored on the user's system may be very large, the user can create lists of preferred diagnosis and procedure codes, i.e., those codes that the user frequently uses. This makes locating an ICD-9 code much easier and faster.

[0817] Profile codes—Profile codes are used for both requisitions and for results. In requisitions, a lab profile includes multiple individual tests, which can be ordered collectively as a profile or individually as needed. In results, a lab profile includes multiple report codes and may include a panel, i.e., multiple tests that have the same report code. Profile codes may be specific to a lab, and may be pre-loaded into the system. As updates become available, these may also loaded into the system automatically, with no action required on the part of the user. Using the Profile Codes function, the user can find codes and print lists of codes. Profile codes are used by both functions accessed from the Orders menu and functions accessed from the Results menu.

[0818] Report Codes—A report code identifies the results of a laboratory clinical test. It differs from an order code in that an order code is the test code used to send an order, and a report code is the code used to return results. A collective set of multiple report codes is referred to as a lab profile. Report codes may be specific to a lab, and may be pre-loaded into the system. As updates become available, these may also loaded into the system automatically, with no action required on the part of the user. Using the Report Codes function, the user can find codes and print lists of codes. Report codes are used by the functions accessed via the Results menu for viewing and reporting on results.

[0819] Specialty List—Specialties define the specific area of medicine or focused approach to health care that a provider or caregiver supplies. Using the Specialty List function, the user may create the specialties that are used throughout the system. Once created, these specialties can then be linked to provider and caregiver records.

[0820] Test Codes—A test code is used to specify what tests need to be performed. Test codes may be specific to a lab and may be loaded into the system based on the transmission mode configuration of the lab. If the lab accepts requisitions electronically, the test codes may be pre-loaded into the system. As updates become available, these may also loaded into the system automatically, with no action required on the part of the user. If the lab only accepts requisitions manually, the test codes can be pre-loaded into the system and/or added through the user interface. Using the Test Codes function, the user can carry out the following functions regardless of the transmission mode configuration for the lab: Finding codes; and Printing lists of codes. Because the number of test codes stored on the system may be very large, the user can create a list of preferred codes, i.e., those codes that the user frequently uses. This makes locating a test code much easier and faster.

[0821] Admin: Manage Resources

[0822] As used herein, resources refer to the manpower, money, facilities, equipment, and supplies used to deliver healthccare services. Using the Manage Resources submenu of the Admin menu, the user can add, remove, and modify these resources as appropriate.

[0823] Admin: Manage Resources: Caregivers

[0824] A caregiver is a person who provides health care services to a patient. For example, physicians, nurses, technicians, and physician's assistants are all caregivers. Using the Caregiver menu option of the Manage Resources submenu, the user can view the caregivers associated with the HDN Business the user is logged on to. The user can search for a caregiver by identifier or the user can perform a general search. The user can also maintain information regarding the caregivers the user does business with. This includes:

[0825] Creating new caregivers

[0826] Maintaining information on existing caregivers

[0827] Deleting existing caregivers

[0828] Printing lists of caregivers

[0829] Admin: Manage System Integration

[0830] System Integration refers to a group of settings that affect certain aspects of the system. These settings fall within four main categories that the user can manage using the corresponding menu options in the Manage System Integration submenu: System Aspect Menu Options Code Sets Local Codes Global Codes Code Translations System Identifiers HDN Business-Specific Identifier Types Site IDs Document Storage Document Routing Configuration Documentation Distribution Lists Network Configuration Network Configuration

[0831] From the Manage System Integration submenu, the user can define and maintain the codes, identifiers, and rules related to these four areas.

[0832] Code Sets

[0833] The user may define and maintain the user's own code sets, such as groups of values or symbols used to represent information such as a patient's employment status, religion, marital status, etc. These values usually appear in drop-down lists from which the user makes a selection. To handle the code sets, the system may be operable to map and translate global and local codes. Global codes refer to user-defined codes that are used uniformly across the entire network (hub). Local codes refer to user-defined codes that are specific to a certain HDN Business.

[0834] Code Translation

[0835] The Code Translation function provides a mechanism for translating codes between different HDN Businesses. Using the Code Translation function, the user can map system codes to HDN Business codes. The purpose of code translations is to support network participants having different sets of valid values for the same field and to provide a mapping from one participant's representation to that of another participant's representation.

[0836] For example, suppose that two hospitals, A and B, are participants in the same network. Hospital A has three Patient Type codes: IN for inpatient, OU for outpatient, and OT for other. Hospital B has four Patient Type codes: I for inpatient, 0 for outpatient, E for emergency, and B for Obstetrics. Through the Code Translation function, both participants can maintain their existing coding systems. The system automatically translates and converts codes when data is shared between participants. Code translation lets a participant receive data from another participant and view that data in their own native domain set using their own coding systems, regardless of who owns the data.

[0837] The idea behind code translations is to provide for each code type, such as relationship code type and religion code type, a set of:

[0838] The system codes

[0839] HDN Business codes (if a network participant wants their own set)

[0840] Mappings for inbound and outbound translation

[0841] The Code Translations menu option provides access to the following information: Select this page . . . To see . . . General Inbound and outbound translations for the code type that the user select The system Codes Set of The system codes for the code type that the user select HDN Business Codes Set of HDN Business codes for the code type that the user select

[0842] The General page of the Code Translations subsystem lists inbound and outbound code translations. Inbound and outbound translations differ based on whether the code is being translated from a system source or HDN Business source. The following table describes these two types of code translation: Code Translation Definition Inbound Mappings from HDN Business codes to system codes Outbound Mappings from system codes to HDN Business codes

[0843] Each system code may map to exactly one code in each defined HDN Business code set. This makes outbound translation possible. Each HDN Business code may be mapped to exactly one system code value. This makes inbound translation possible. The system set of codes within a code set may include a superset of all possible code descriptions that might be used by any HDN Business set in the network.

[0844] The System Codes page of the Code Translations subsystem lists the set of system codes for the code type that the user selects, such as MS for marital status. The system codes then appear in the Outbound section on the General page. For example, the system marital status codes appear on the System Codes page after the user selects MS as the code type. If the user clicks the General page button to see the General page, the system marital status code set appears in the Outbound section of the General page.

[0845] The HDN Business Codes page of the Code Translations subsystem lists the set of HDN Business codes for the code type that the user select, such as MS for marital status. The HDN Business codes then appear in the Inbound section on the General page. For example, the system marital status codes appear on the HDN Business page after the user selects MS as the code type. If the user clicks the General page button to see the General page, the HDN Business-specific marital status code set appears in the Inbound section of the General page.

[0846] System Identifiers

[0847] A system identifier is a string of characters used as a label, such as BAN for Billing Account Number. There are two categories of system identifiers: Caregiver and Patient. The Registration flag is used by the identifier labels Insurance Code and Patient Account. Each HDN Business may define one registration label for each type (Caregiver, Patient or Payer). For example the registration label for Payer type may be Insurance Code and the registration label for Patient Type may be Patient Account. Because identifiers are categorized, only the patient identifiers appear in the Patient subsystem. These categories are used to store IDs originating from external systems such as Practice Management Systems. These identifiers help distinguish between the various types of account numbers. Identifiers might also be used to distinguish between types of payer account numbers or types of caregiver certificate numbers.

[0848] Document Storage

[0849] Medical personnel and related administrative staff receive many reports and other documents in paper form. Often, these are generated electronically by various systems, then printed and distributed by a manual delivery method. In the preferred embodiment, the system allows its participants to automatically receive electronic images of printed documents that would otherwise have to be received through interoffice mail, fax, US Mail, or some other physical delivery method. The Document Routing Configuration subsystem allows the user to manage and configure the receipt and distribution of documents.

[0850] Routing and Distribution—Routing allows the user to map a document recipient to a user. A document's routing specifies its first point of entry into the system. Distribution defines which users should receive the document in addition to the first recipient. For example, a document, such as a patient's insurance statement, might be addressed to a physician, but the document should also go to the claims administrator working in his or her practice. Thus, the document should be routed to the claims administrator. The claims administrator might need to distribute or forward the insurance statement to several clerks. Thus, the document should be routed to the specific clerks.

[0851] Document Routing

[0852] Routing allows the user to specify a recipient for a document. A routing configuration is the “path” the user wants a document to take from its source to a destination. Through the Document Routing Configuration menu option of the Manage System Integration submenu, the user sets up the rules that determine how and to whom documents are routed. Documents routed by these rules may then be accessed through the View Documents menu option of the User menu. The user can select the Document Routing Configuration menu option to access the following information: Select this page . . . To see . . . Routing Rules for routing the user's documents Sources Client sources from which the user receives documents Types Type of documents that the user receive

[0853] Using the Routing page, the user creates the rules for routing the user's documents. The user can set up two types of routing rules: General Routing Rules and Document-Specific Routing Rules.

[0854] General routing rules are for documents from a specific source that are to be sent to a single person. For example, if all incoming electronic clinical results documents from an SBCL lab in St. Louis are to be sent to a lab tech in the user's office regardless of to whom the results are addressed, the user can set up a rule that automatically routes documents of that category from the specific source to that person. This is a general routing rule. The user creates general routing rules for a source by selecting a pre-defined category of documents, entering an addressee, and then selecting a user to whom electronic documents of the selected category that are addressed to the addressee are routed.

[0855] Document-specific routing rules are for specific types of documents that are to be sent to a single person. For example, if all incoming electronic radiology documents are to be sent to the radiologist in the user's office regardless of to whom the results are addressed, the user can set up a rule that automatically routes documents of that type to that person. This is a document-specific routing rule. The user creates document-specific routing rules for a source by selecting a document type, entering an addressee, and then selecting a user to whom electronic documents of the selected type that are addressed to the addressee are routed.

[0856] When the user sets up document routing rules, the user first specifies the source of the document. The Sources page is used to define these sources. The Sources page lists the name and description of each source.

[0857] When the user creates document-specific routing rules, the user selects a document type. The Types page is used to define document types. Each document type falls in a system-defined category. The following table lists common document types and their categories: Category Document Type Administrative Patient history Patient demographics Clinical Radiology Diagnosis Patient Evaluation Financial Payments From Patient Billing

[0858] Document Distribution Lists

[0859] A document distribution is like a document routing in that it uses rules to automatically distribute electronic documents that have been routed to a specific user. Documents distributed by these rules are then accessed through the View Documents function of the User menu. However, unlike a routing, which only allows the user to automatically send a document to a single user, document distribution allows the user to create a list of users to whom a single document is sent.

[0860] The Document Distribution Lists function allows the user to create general distribution rules for a “routed to user” by selecting a system-defined category of documents and then selecting users to whom electronic documents of the selected category are distributed. The user can also create document-specific distribution rules for a “routed to user” by selecting a document type and then selecting users to whom electronic documents of the selected type are distributed.
